O come, let us sing unto the LORD: let us make a joyful noise to the rock of our salvation.

Augustine of Hippo
1. I could wish, brethren, that we were rather listening to our father: but even this is a good thing, to obey our father. Since therefore he who deigneth to pray for us, hath ordered us, I will speak unto you, beloved, what from the present Psalm Jesus Christ our common Lord shall deign to give us. Now the title of the Psalm is "David's Song of praise." The "Song of praise" signifieth both cheerfulness, in that it is a song; and devotion, for it is praise. For what ought a man to praise more than that which pleaseth him so, that it is impossible that it can displease him? In the praising of God therefore we praise with security. There he who praiseth is safe, where he feareth not lest he be ashamed for the object of his praise. Let us therefore troth praise and sing; that is, let us praise with cheerfulness and joy. But what we are about to praise, this Psalm in the following verses showeth us. ...
2. "O come, let us sing unto the Lord" (ver. 1). He calleth us to a great banquet of joy, not one of this world, but in the Lord. For if there were not in this life a wicked joy which is to be distinguished from a righteous joy, it would be enough to say, "Come, let us rejoice;" but he has briefly distinguished it. What is it to rejoice aright? To rejoice in the Lord. Thou shouldest piously joy in the Lord, if thou dost wish safely to trample upon the world. But what is the word, "Come "? Whence doth He call them to come, with whom he wisheth to rejoice in the Lord; except that, while they are afar, they may by coming draw nearer, by drawing nearer they may approach, and by approaching rejoice? But whence are they afar? Can a man be locally distant from Him who is everywhere? ...It is not by place, but by being unlike Him, that a man is afar from God. What is to be unlike Him? it meaneth, a bad life, bad habits; for if by good habits we approach God, by bad habits we recede from God. ....
Himself, as David wrote it by inspiration. (Worthington)
Complutensian Septuagint, "It is without a title in Hebrew. "St. Paul (Hebrews iv. 7.) quotes it as the work of David. But this is only done incidentally, and it may have been written by the descendants of Moses, (Psalm lxxxix.; Calmet) as the apostle only says, in David, (Haydock) referring to the psalter, which the common opinion attributed to him. (Calmet)
This opinion, it must be owned, acquires hereby great authority, (Haydock) as an inspired writer could not mistake; and Calmet himself, on the epistle to the Hebrews, doubts not but as the drift of the apostle requires, he attributed this psalm to David. (Berthier, T. vi.)
It might be used in the removal of the ark (Muis) and contains an exhortation to the Jews to return to the service of God, under king Josias, (Theodoret) or after the captivity, (Calmet) or at the preaching of the gospel. (Eusebius)
