Psalms 55:1

Give ear to my prayer, O God,.... Which was for that which is just and right, and equitable to be given, as the word n used signifies; being promised in the covenant of grace, ratified and confirmed by the blood of Christ, Not only David was a man much given to prayer, as well as was the sweet psalmist of Israel; but the Messiah, as man, was much and often engaged in this work, in the days of his flesh, Luke 6:12;

and hide not thyself from my supplication; made for mercies and blessings, which spring from the free grace and goodness of God, which is the sense of the word o here used; and such are all mercies, whether temporal or spiritual; for none are merited by men: and from his supplication for such things the psalmist desires, that as he would not be as one deaf to him, so that he would not hide his eyes, or refuse to look upon him, and deny his, requests; see Isaiah 1:15.

n תפלתי "orationem meam", i.e. "secundum judicium"; so Arana. o תחנתי "my supplication for grace", Ainsworth.
