Ye are the light of the world We are all the children of light, after having been enlightened by faith, and are commanded to carry in our hands "burning lamps," (that we may not wander in darkness,) and even to point out to others the way of life, (Luke 12:35.) But, as the preaching of the Gospel was committed to the apostles above others, and is now committed to the pastors of the Church, this designation is given to them, in a peculiar manner, by Christ. "They are placed in this rank on the condition, that they shall shine, as from an elevated situation, on all others." He subjoins two comparisons. A city placed on a mountain cannot be concealed; and a candle, when it has been lighted, is not usually concealed, (verse 15.) This means, that they ought to live in such a manner, as if the eyes of all were upon them. And certainly, the more eminent a person is, the more injury he does by a bad example, if he acts improperly. Christ, therefore, informs the apostles, that they must be more careful to live a devout and holy life, than unknown persons of the common rank, because the eyes of all are directed to them, as to lighted candles; and that they must not be endured, if their devotion, and uprightness of conduct, do not correspond to the doctrine of which they are ministers. Mark and Luke appear to apply the comparison in a different manner: for there Christ gives a general admonition, that they ought to take particular care, lest any one, trusting to the darkness, indulge freely in sin, because what is hidden for a time will afterwards be revealed. But perhaps the discourses related by both of them are detached from the immediate context.
The light of the world - The light of the world often denotes the sun, John 11:9. The sun renders objects visible, shows their form, their nature, their beauties, their deformities. The term light is often applied to religious teachers. See Matthew 4:16; Luke 2:32; John 1:4; John 8:12; Isaiah 49:6. It is pre-eminently applied to Jesus in these places, because he is, in the moral world, what the sun is in the natural world. The apostles, Christian ministers, and all Christians, are lights of the world, because they, by their instructions and example, show what God requires, what is the condition of man, what is the way of duty, peace, and happiness the way that leads to heaven.
A city that is set on a hill - Many of the cities of Judea were placed on the summits or sides of mountains, and could be seen from afar. Perhaps Jesus pointed to such a city, and told his disciples that they were like it. Their actions could not be hid. The eyes of the world were upon them. They must be seen; and as this was the case, they ought to be holy, harmless, and undefiled.
Maundrell, Jowett, and others suppose that the Sermon on the Mount was delivered in the vicinity of the present city of Safed, or "the Horns of Huttin" (see the notes at Matthew 5:1), and that this city may have been in his eye, and may have been directly referred to by the Saviour when he uttered this sentiment. It would give additional force and beauty to the passage to suppose that he pointed to the city. Of this Dr. Thomson (The Land and the Book, vol. i. pp. 420, 421) says, "The shape of the hill is a well-described oval, and the wall corresponds to it. The bottom of the outer ditch is now a very flourishing vineyard, and the entire circuit is not far from half a mile. The wall is mostly modern, but built on one more ancient, portions of which can be seen on the east side. The interior summit rises about a hundred feet higher than this wall, and was a separate castle, strongly defended. Here are beveled stones, as heavy, and as aged in appearance, as those of the most celebrated ruins in the country; and they prove that this has been a place of importance from a remote age. These ancient parts of the castle render it all but certain that there was then a city or citadel on this most conspicuous 'hill' top; and our Lord might well point to it to illustrate and confirm his precept. The present Hebrew name is Zephath, and may either refer to its elevation like a watchtower, or to the beauty and grandeur of the surrounding prospects. Certainly they are quite sufficient to suggest the name. There lies Gennesaret, like a mirror set in framework of dark mountains and many-faced hills. Beyond is the vast plateau of the Hauran, faintly shading with its rocky ranges the utmost horizon eastward. Thence the eye sweeps over Gilead and Bashan, Samaria and Carmel, the plains of Galilee, the coasts of Phoenicia, the hills of Naphtali, the long line of Lebanon, and the lofty head of Hermen - a vast panorama, embracing a thousand points of historic and sacred interest."
Ye are the light of the world - That is, the instruments which God chooses to make use of to illuminate the minds of men; as he uses the sun (to which probably he pointed) to enlighten the world. Light of the world, נר עולם ner olam, was a title applied to the most eminent rabbins. Christ transfers the title from these, and gives it to his own disciples, who, by the doctrines that he taught them, were to be the means of diffusing the light of life throughout the universe.
A city that is set on a hill - This place may receive light from the following passage in Maundrell's Travels. "A few points toward the north (of Tabor) appears that which they call the Mount of Beatitudes, a small rising, from which our blessed Savior delivered his sermon in the fifth, sixth, and seventh chapters of Matthew. (See the note on Matthew 5:5). Not far from this little hill is the city Saphet, supposed to be the ancient Bethulia. It stands upon a very eminent and conspicuous mountain, and is Seen Far and Near. May we not suppose that Christ alludes to this city, in these words of his, A city set on a hill cannot be hid?" p. 115. Quesnell remarks here: "The Christian life is something very high and sublime, to which we cannot arrive without pains: while it withdraws us from the earth, and carries us nearer heaven, it places us in view, and as a mark, to the malice of carnal men."
Ye are the (f) light of the world. A city that is set on an hill cannot be hid.
(f) You shine and give light by being made partakers of the true light.
Ye are the light of the world,.... What the luminaries, the sun and moon, are in the heavens, with respect to corporal light, that the apostles were in the world with regard to spiritual light; carrying and spreading the light of the Gospel not only in Judea, but all over the world, which was in great darkness of ignorance and error; and through a divine blessing attending their ministry, many were turned from the darkness of Judaism and Gentilism, of sin and infidelity, to the marvellous light of divine grace. The Jews were wont to say, that of the Israelites in general, and particularly of their sanhedrim, and of their learned doctors, what Christ more truly applies here to his apostles; they observe (l), that
"on the fourth day it was said, "let there be light": which was done with respect to the Israelites, because they are they , "which give light to the world", as it is written, Daniel 12:3'
And in another place (m), say they,
"how beautiful are the great ones of the congregation, and the wise men, who sit in the sanhedrim! for they are they , "that enlighten the world", the people of the house of Israel.''
So. R. Meir, R. Akiba his disciple, and R. Judah the prince, are each of them called (n) , "the light of the world"; as R. Jochanan ben Zaccai is by his disciples, , "the lamp of the world" (o): and it was usual for the head of a school, or of an university to be styled (p) , "the light of the world"; but this title much better agrees and suits with the persons Christ gives it to, who, no question, had a view to those exalted characters the Jews gave to their celebrated Rabbins. A city that
is set on an hill cannot be hid; alluding either to Nazareth, where he was educated, and had lately preached, which was built on an hill, from the brow of which the inhabitants sought to have cast him headlong, Luke 4:29 or to Capernaum, which, on account of its height, is said to be
exalted unto heaven, Matthew 11:23 or to the city of Jerusalem, which was situated on a very considerable eminence. The land of Israel, the Jews say (q), was higher than all other lands; and the temple at Jerusalem was higher than any other part of the land of Israel. And as a city cannot be hid which is built on a high place, so neither could, nor ought the doctrines which the apostles were commissioned to preach, be hid, or concealed from men: they were not to shun to declare the whole counsel of God, nor study to avoid the reproaches and persecutions of men; for they were to be "made a spectacle"; to be set as in a public theatre, to be seen by "the world, angels, and men".

Ye are the light of the world--This being the distinctive title which our Lord appropriates to Himself (John 8:12; John 9:5; and see John 1:4, John 1:9; John 3:19; John 12:35-36) --a title expressly said to be unsuitable even to the highest of all the prophets (John 1:8) --it must be applied here by our Lord to His disciples only as they shine with His light upon the world, in virtue of His Spirit dwelling in them, and the same mind being in them which was also in Christ Jesus. Nor are Christians anywhere else so called. Nay, as if to avoid the august title which the Master has appropriated to Himself, Christians are said to "shine"--not as "lights," as our translators render it, but--"as luminaries in the world" (Philippians 2:15); and the Baptist is said to have been "the burning and shining"--not "light," as in our translation, but "lamp" of his day (John 5:35). Let it be observed, too, that while the two figures of salt and sunlight both express the same function of Christians--their blessed influence on their fellow men--they each set this forth under a different aspect. Salt operates internally, in the mass with which it comes in contact; the sunlight operates externally, irradiating all that it reaches. Hence Christians are warily styled "the salt of the earth"--with reference to the masses of mankind with whom they are expected to mix; but "the light of the world"--with reference to the vast and variegated surface which feels its fructifying and gladdening radiance. The same distinction is observable in the second pair of those seven parables which our Lord spoke from the Galilean Lake--that of the "mustard seed," which grew to be a great overshadowing tree, answering to the sunlight which invests the world, and that of the "leaven," which a woman took and, like the salt, hid in three measures of meal, till the whole was leavened (Matthew 13:31-33).
A city that is set on an hill cannot be hid--nor can it be supposed to have been so built except to be seen by many eyes.
Ye are the light of the world. The business of the church is not only to save, but to enlighten. Christ is light, and his disciples must be light.
A city set on an hill. Anciently cities, for the sake of defense, were placed on hills. Such cities are seen from afar. So must the church give forth its light.
Ye are the light of the world - If ye are thus holy, you can no more be hid than the sun in the firmament: no more than a city on a mountain - Probably pointing to that on the brow of the opposite hill.
