Jamieson, Fausset and Brown on Psalms 88:1-2

PSALM 88

Psa 88:1-18. Upon Mahalath--either an instrument, as a lute, to be used as an accompaniment (Leannoth, "for singing") or, as others think, an enigmatic title (see on Psa 5:1, Psa 22:1, and Psa 45:1, titles), denoting the subject--that is, "sickness or disease, for humbling," the idea of spiritual maladies being often represented by disease (compare Psa 6:5, 6; 22:14, 15, &c.). On the other terms, see on Psa 42:1 and Psa 32:1. Heman and Ethan (see on Psa 89:1, title) were David's singers (1Ch 6:18, 33; 15:17), of the family of Kohath. If the persons alluded to (1Ki 4:31; 1Ch 2:6), they were probably adopted into the tribe of Judah. Though called a song, which usually implies joy (Psa 83:1), both the style and matter of the Psalm are very despondent; yet the appeals to God evince faith, and we may suppose that the word "song" might be extended to such compositions.

1-2. Compare on the terms used, Psa 22:2; 31:2.
