The prayers of David the son of Jesse are ended. We have before observed that this was not without cause added by Solomon, (if we may suppose him to have put the matter of this psalm into the form of poetical compositions) not only that he might avoid defrauding his father of the praise which was due to him, but also to stir up the Church the more earnestly to pour forth before God the same prayers which David had continued to offer even with his last breath. Let us then remember that it is our bounden duty to pray to God, both with unfeigned earnestness, and with unwearied perseverance, that he would be pleased to maintain and defend the Church under the government of his Son. The name of Jesse, the father of David, seems to be here introduced to bring to remembrance David's origin, that the grace of God may appear the more illustrious in having raised from the sheepfold a man of mean birth, as well as the youngest and the least esteemed among his brethren, and in having advanced him to so high a degree of honor, as to make him king over the chosen people.
The prayers of David the son of Jesse are ended - This is not found in the Syriac. The following is added in that version at the close of the psalm: "The end of the Second Book." In regard to this twentieth verse, it is quite clear that it is no part of the psalm; and it is every way probable that it was not placed here by the author of the psalm, and also that it has no special and exclusive reference to this psalm, for the psalm could in no special sense be called "a prayer of David." The words bear all the marks of having been placed at the close of a collection of psalms, or a division of the Book of Psalm, to which might be given as an appropriate designation, the title "The Prayers of David, the son of Jesse;" meaning that that book, or that division of the book, was made up of the compositions of David, and might be thus distinguished from other portions of the general collection. This would not imply that in this part of the collection there were literally no other psalms than those which had been composed by David, or that none of the psalms of David might be found in other parts of the general collection, but that this division was more entirely made up of his psalms, and that the name might therefore be given to this as his collection. It may be fairly inferred from this, that there was such a collection, or that there were, in the Book of Psalm, divisions which were early recognized. See the General Introduction. Dr. Horsley supposes, however, that this declaration, "The prayers of David the son of Jesse are ended," pertains to this psalm alone, as if David had nothing more to pray for or to wish than what was expressed in these glowing representations of the kingdom of the Messiah, and of the happy times which would be enjoyed under his rule.
The prayers of David the son of Jesse are ended - This was most probably the last Psalm he ever wrote. There may be several in the after part of this book which were written by him; but they were probably composed in a former period of his life, for this was the end of the poetic prayers of David the son of Jesse. Those that were found afterwards have got out of their proper connection.
The (q) prayers of David the son of Jesse are ended.
(q) Concerning his son Solomon.
The prayers of David the son of Jesse are ended. The Septuagint version renders it, the hymns. This psalm is thought by some to be the last that was written by David, though put in this place; and it is certain that the psalms are not always placed in the order of time in which they were written: this being, as is supposed, made by him in his old age, when Solomon his son was appointed and set upon his throne by his order; on account of which he composed it, with a view to the Messiah, the antitype of Solomon. Or, as others, this is the last of the psalms, which were put together and digested in order by David himself; the rest that follow being collected by Hezekiah or the Levites. Aben Ezra mentions it as the sense of some of their interpreters,
"then shall be fulfilled the prayers of the son of Jesse;''
that is, as R. Joseph Kimchi explains it, when those consolations are completed, then the prayers of David the son of Jesse shall be fulfilled. The sense is, when all the things spoken of in this psalm, concerning the Messiah and his kingdom, should be accomplished, then the prayers of David, and so of every good man, his hearty wishes and desires, will then be answered, and have their full effect, and not till then. This verse seems to be written not by David, for the psalm itself ends with "Amen and Amen"; but by some collector of the Psalm: it is not in the Arabic version, in the room of which is "Hallelujah"; and in the Syriac version it is, "the end of the second book". The first book of Psalm ends with the forty first Psalm. The whole is divided into five parts by the Jews; observed by Origen (x) and Hilarius (y), and others.

ended--literally, "finished," or completed; the word never denotes fulfilment, except in a very late usage, as in Ezra 1:1; Daniel 12:7.
Superscription of the primary collection. The origin of this superscription cannot be the same as that of the doxology, which is only inserted between it and the Psalm, because it was intended to be read with the Psalm at the reading in the course of the service (Symbolae, p. 19). כּלוּ = כּלּוּ, like דּחוּ in Ps 36:13, כּסּוּ, Psalm 80:11, all being Pual forms, as is manifest in the accented ultima. A parallel with this verse is the superscription "are ended the words of Job" in Job 31:40, which separates the controversial speeches and Job's monologue from the speeches of God. No one taking a survey of the whole Psalter, with the many Psalm of David that follow beyond Ps 72, could possibly have placed this key-stone here. If, however, it is more ancient than the doxological division into five books, it is a significant indication in relation to the history of the rise of the collection. It proves that the collection of the whole as it now lies before us was at least preceded by one smaller collection, of which we may say that it extended to Ps 72, without thereby meaning to maintain that it contained all the Psalm up to that one, since several of them may have been inserted into it when the redaction of the whole took place. But it is possible for it to have contained Ps 72, wince at the earliest it was only compiled in the time of Solomon. The fact that the superscription following directly upon a Psalm of Solomon is thus worded, is based on the same ground as the fact that the whole Psalter is quoted in the New Testament as Davidic. David is the father of the שׁיר ה, 2-Chronicles 29:27, and hence all Psalm may be called Davidic, just as all משׁלים may be called Salomonic, without meaning thereby that they are all composed by David himself.
The prayer - This psalm is the last which David composed: for this was wrote but a little before his death.
