This psalm, though without a title, was probably written by David, since it begins and ends as the former does, as Aben Ezra observes; and to him the Septuagint, Vulgate Latin, and all the Oriental versions, ascribe it.
The inscription of the Syriac version is,"a psalm of David, when he went to worship before the ark of the Lord with the priests; and as to us, it teaches us confession and prayer; and intimates to us the constitution of the beginning of the creatures; and declares some things concerning the angels.'
'Some copies of the Septuagint version have it,"a psalm of David concerning the constitution of the world;''which indeed is the subject matter of it; for it treats of the creation of all things, of the heavens and the earth, and of all creatures in them; and of the providence of God in taking care of them.
Christ is the divine Person addressed and described throughout the whole, as appears from the quotation of Ps 104:5 and the application of it to him in Heb 1:7.Bless the Lord, O my soul,.... As for the blessings of grace and mercy expressed in the preceding psalm, so on account of the works of creation and providence, enumerated in this; in which Christ has an equal concern, as in the former.
O Lord my God, thou art very great; the Messiah, who is Jehovah our righteousness, Lord of all, truly God, and the God of his people; see Joh 20:28 and who is great, and very great, in his divine Person, being the great God, and our Saviour; great in all his works of creation, providence, and redemption; great in all his offices of Prophet, Priest, and King; a Saviour, and a great one; the great Shepherd of the Sheep; the Man, Jehovah's Fellow.
