INTRODUCTION TO PSALM 37 A Psalm of David. This psalm, it is very probable, was written at the same time, and upon the same occasion, with the former; and describes the different states of good and bad men; and is full of exhortations, instructions, and advice to the people of God; intermixed with various encouraging promises. A late learned writer (h) thinks it was written for Mephibosheth's consolation under Ziba's calumny. (h) Delaney's Life of King David, vol. 2. p. 219.
