This psalm is very much like that which goes next before it; it was penned upon a like occasion, when David was both in danger of trouble and in temptation to sin; it begins as that did, "Be merciful to me;" the method also is the same. I. He begins with prayer and complaint, yet not without some assurance of speeding in his request (Psa 57:1-6). II. He concludes with joy and praise (Psa 57:7-11). So that hence we may take direction and encouragement, both in our supplications and in our thanksgivings, and may offer both to God, in singing this psalm. To the chief musician, Al-taschith, Michtam of David, when he fled from Saul in the cave.
