To the chief Musician, [A Psalm] of David, to bring to remembrance. This psalm, according to Kimchi, was composed by David when he fled from Saul, or from Absalom; so Theodoret; but if at either of those times, it is most likely to be the latter, since the following psalm, it is certain, was penned when he was an old man, Ps 69:9; the word translated "to bring to remembrance" is thought, by Aben Ezra, to be the first word of some pleasant song; see Ps 38:1.
The Targum paraphrases it, to remember the use of the frankincense; alluding to Le 2:2; Jarchi says it signifies prayer, and refers to Ps 20:7, as instances of the use of the word in such a sense; and so this psalm is composed by the psalmist in a petitionary way, to put the Lord in remembrance of his afflictions, and of his promises of help and deliverance, which he prays for; see Ps 132:1; and that he would avenge him on his enemies, and show respect to his friends; or it was written to refresh his own memory with his present state, and to put him in mind from whence he might expect help and salvation.
The title of the psalm in the Arabic version is, and so in the Vulgate Latin, following the Septuagint,"a remembrance that the Lord had saved him:''and in the Syriac version,"a psalm of David as to the letter, when he sent Joab to take Shemuah (Sheba), who rebelled; also a supplication of the righteous, and even of Christ himself.'
'And seeing this follows upon the preceding, and may be reckoned an appendix to it, and there are some things in it which manifestly refer to the latter part of that, and the whole is detached from the fortieth psalm, with which it agrees, a few words only excepted, which manifestly belongs to the Messiah; it is right to understand this of him; Ps 40:13.
Ver. 1. [Make haste], O God, to deliver me,.... The phrase, "make haste", is supplied from the following clause in Ps 40:13; it is, "be pleased, O Lord", or "Jehovah".
