from my youth up
88:15 from my youth up. Assuming this indeed to be a Messianic psalm, this verse gives an insight into the opposition suffered by Christ even as he was growing up—a subject hardly touched on in the New Testament records of His life.
Psalm 89 (title) Maschil. This psalm is the last of the thirteen or fourteen Maschil psalms. Written by Ethan, (apparently the brother of Heman—I Kings 4:31), its tone of victory contrasts sharply (and appropriately) with that of Psalm 88, written by Heman. Although Heman and Ethan were probably of the tribe of Judah (I Chronicles 2:6), there were also two Levitical singers with these names associated with Asaph (I Chronicles 15:17,19), so the precise identification of Heman and Ethan is uncertain. With its fifty-two verses, Psalm 89 is the third longest of the psalms (after Psalm 119 and 78).
