22 I will lay the key of the house of David on his shoulder. He will open, and no one will shut. He will shut, and no one will open.

And the key of the house of David. [1] This expression is metaphorical, and we need not spend much time, as some do, in drawing from it an allegorical meaning; for it is taken from an ordinary custom of men. The keys of the house are delivered to those who are appointed to be stewards, that they may have the full power of opening and shutting according to their own pleasure. By "the house of David" is meant "the royal house." This mode of expression was customary among the people, because it had been promised to David that his kingdom would be for ever. (2 Samuel 7:13; Psalm 132:11, 12.) That is the reason why the kingdom was commonly called "the house of David." The key is put in the singular number for keys. Though "keys" are usually carried in the hands, yet he says that they are laid on the shoulders, [2] because he is describing an important charge. Yet nothing more is meant than that the charge and the whole government of the house are committed to him, that he may regulate everything according to his pleasure; and we know that the delivering of keys is commonly regarded as a token of possession. Some commentators have viewed this passage as referring to Christ, but improperly; for the Prophet draws a comparison between two men, Shebna and Eliakim. Shebna shall be deprived of his office, and Eliakim shall succeed him. What has this to do with Christ? For Eliakim was not a type of Christ, and the Prophet does not here describe any hidden mystery, but borrows a comparison from the ordinary practice of men, as if the keys were delivered to one who has been appointed to be steward, as has been already said. For the same reason Christ calls the office of teaching the word, (Matthew 16:19,) "the keys of the kingdom of heaven;" so that it is idle and foolish to spend much time in endeavoring to find a hidden reason, when the matter is plain, and needs no ingenuity. The reason is, that ministers, by the preaching of the word, open the entrance into heaven, and lead to Christ, who alone is "the way." (John 14:6.) By the keys, therefore, he means here the government of the king's house, because the principal charge of it would be delivered to Eliakim at the proper time.
1 - "As the robe and the baldric, mentioned in the preceding verse, were the ensigns of power and authority, so likewise was the key the mark of office, either sacred or civil." -- Lowth
2 - "To comprehend how the key could be borne on the shoulder, it will be necessary to say somewhat of the form of it; but, without entering into a long disquisition, and a great deal of obscure learning, concerning the locks and keys of the ancients, it will be sufficient to observe, that one sort of keys, and that probably the most ancient, was of considerable magnitude, and, as to the shape, very much bent and crooked. Homer, Odyss. 21:6, describes the key of Ulysses's store-house as eukampes, of a large curvature; which Eustathius explains by saying it was drepanoeides, in shape like a reap-hook. The curve part was introduced into the key-hole, and, being properly directed by the handle, took hold of the bolts within, and moved them from their places. We may easily collect from this account, that such a key would lie very well upon the shoulder; that it must be of some considerable size and weight, and could hardly be commodiously carried otherwise. Ulysses's key was of brass, and the handle of ivory; but this was a royal key; the more common ones were probably of wood." -- Lowth
And the key - A key is that by which a house is locked or opened. To possess that is, therefore, to have free access to it, or control over it. Thus we give possession of a house by giving the "key" into the hands of a purchaser, implying that it is his; that he has free access to it; that he can close it when he pleases, and that no other one, without his permission, has the right of access to it.
Of the house of David - Of the house which David built for his royal residence; that is, of the palace. This house was on Mount Zion; and to have the key of that house was to have the chief authority at court, or to be prime minister (see the note at Isaiah 22:15). To be put in possession of that key, therefore, was the mark of office, or was a sign that he was entrusted with the chief authority in the government.
Will I lay upon his shoulder - (see Isaiah 9:6). This seems to have been designed as an emblem of office. But in what way it was done is unknown. Lowth supposes that the key was of considerable magnitude, and was made crooked, and that thus it would lie readily on the shoulder. He has observed also, that this was a well-known badge or emblem of office. Thus the priestess of Ceres is described as having a key on the shoulder (Callim. "Ceres," ver. 45); and thus in AEschyl. "Supp." 299, a female high in office is described as having a key. But it is not known in what way the key was borne. It may have been borne on the shoulder, being so made as to be easily carried there; or it may have been attached to the shoulder by a belt or strap, as a sword is; or it may have been a mere emblem or figure fashioned into the robe, and worn as a sign of office; or the figure of a key may have been worn on the shoulder as an epaulet is now, as a sign of office and authority. If the locks were made of wood, as we have reason to suppose, then the key was probably large, and would answer well for a sign of office. 'How much was I delighted when I first saw the people, especially the Moors, going along the streets with each his key on his shoulder. The handle is generally made of brass (though sometimes of silver), and is often nicely worked in a device of filigrane. The way it is carried is to have the corner of a kerchief tied to the ring; the key is then placed on the shoulder, and the kerchief hangs down in front. At other times they have a bunch of large keys, and then they have half on one side of the shoulder, and half on the other. For a man thus to march along with a large key on his shoulder, shows at once that he is a person of consequence. "Raman is in great favor with the Modeliar, for he now carries the key." "Whose key have you got on your shoulder?" "I shall carry my key on my own shoulder."' - (Roberts)
So he shall open - This phrase means, that he should have the highest authority in the government, and is a promise of unlimited power. Our Saviour has made use of the same expression to denote the unlimited power conferred on his apostles in his church Matthew 16:19; and has applied it also to himself in Revelation 3:7.
And the key of the house of David will I lay upon his shoulder - As the robe and the baldric, mentioned in the preceding verse, were the ensigns of power and authority, so likewise was the key the mark of office, either sacred or civil. The priestess of Juno is said to be the key-bearer of the goddess, κλειδουχος Ἡρας· Aeschyl. Suppl. 299. A female high in office under a great queen has the same title: -
Καλλιθοη κλειδουχος Ολυμπιαδος βασιλειης.
"Callithoe was the key-bearer of the Olympian queen."
Auctor Phoronidis ap. Clem. Alex. p. 418, edit. Potter. This mark of office was likewise among the Greeks, as here in Isaiah, borne on the shoulder; the priestess of Ceres, κατωμαδιαν εχε κλαιδα, had the key on her shoulder. Callim. Ceres, verse 45. To comprehend how the key could be borne on the shoulder, it will be necessary to say something of the form of it: but without entering into a long disquisition, and a great deal of obscure learning, concerning the locks and keys of the ancients, it will be sufficient to observe, that one sort of keys, and that probably the most ancient, was of considerable magnitude, and as to the shape, very much bent and crooked. Aratus, to give his reader an idea of the form of the constellation Cassiopeia, compares it to a key. It must be owned that the passage is very obscure; but the learned Huetius has bestowed a great deal of pains in explaining it, Animadvers. in Manilii, lib. 1:355; and I think has succeeded very well in it. Homer Odyss. Isaiah 21:6, describes the key of Ulysses' storehouse as ευκαμπης, of a large curvature; which Eustathius explains by saying it was δρεπανοειδης, in shape like a reaphook. Huetius says the constellation Cassiopeia answers to this description; the stars to the north making the curve part, that is, the principal part of the key; the southern stars, the handle. The curve part was introduced into the key-hole; and, being properly directed by the handle, took hold of the bolts within, and moved them from their places. We may easily collect from this account, that such a key would lie very well upon the shoulder; that it must be of some considerable size and weight, and could hardly be commodiously carried otherwise. Ulysses' key was of brass, and the handle of ivory: but this was a royal key. The more common ones were probably of wood. In Egypt they have no other than wooden locks and keys to this day; even the gates of Cairo have no better. Baumgarten, Peregr. 1:18. Thevenot, part ii., chap. 10. But was it not the representation of a key, either cut out in cloth and sewed on the shoulder of the garment, or embroidered on that part of the garment itself? The idea of a huge key of a gate, in any kind of metal, laid across the shoulder, is to me very ridiculous.
In allusion to the image of the key as the ensign of power, the unlimited extent of that power is expressed with great clearness as well as force by the sole and exclusive authority to open and shut. Our Savior, therefore, has upon a similar occasion made use of a like manner of expression, Matthew 16:19; and in Revelation 3:7 has applied to himself the very words of the prophet.
And the (x) key of the house of David will I lay upon his shoulder; so he shall open, and none shall shut; and he shall shut, and none shall open.
(x) I will commit to him the full charge and government of the king's house.
And the key of the house of David will I lay upon his shoulder,.... In allusion either to magistrates carrying a key on their shoulder, hanging down from thence, having a hook at one end of it fit for that purpose; or having one embroidered on that part of their garment: or one carried before them by their servants. It regards either the keys of the temple; or rather the key of the king's house, which it was proper should be delivered to him as treasurer and steward of it; the Targum takes in both,
"and I will give the key of the house of the sanctuary, and the government of the house of David, into his hand.''
In the mystical sense, Christ is said to have this key, Revelation 3:7 where the following words are applied to him:
so he shall open, and none shall shut; and he shall shut, and none shall open; all which is expressive of the government of the church being on his shoulders, and of his absolute and uncontrollable power over it; who opens the treasures of his word, of his grace, and of wisdom and knowledge, and communicates them unto, and shuts or hides them from, whom he pleases; who opens and shuts the doors of his church, his house, and lets in, and keeps out, whom he thinks fit; and who also opens and shuts the door of the kingdom of heaven, and introduces into it his own people, and excludes others.
key--emblem of his office over the house; to "open" or "shut"; access rested with him.
upon . . . shoulder--So keys are carried sometimes in the East, hanging from the kerchief on the shoulder. But the phrase is rather figurative for sustaining the government on one's shoulders. Eliakim, as his name implies, is here plainly a type of the God-man Christ, the son of "David," of whom Isaiah (Isaiah 9:6) uses the same language as the former clause of this verse. In Revelation 3:7, the same language as the latter clause is found (compare Job 12:14).
The key - The government, the power of opening and shutting, of letting men into it, or putting them out of it, whereof a key is a fit emblem. Shoulder - He mentions the shoulder rather than the hand, in which keys are commonly carried, from some ceremony then in use, of carrying a key upon the shoulder of the officer of state.
