John Gill Commentary Psalms 88:9

"Mine eye wasteth away by reason of affliction: I have called daily upon thee, O Jehovah; I have spread forth my hands unto thee." — Psalms 88:9 (ASV)

Mine eye mourneth by reason of affliction
Or dropped tears, as the Targum, by which grief was vented; see (Psalms 6:7) .

Lord, I have called daily upon you, I have stretched out my hands unto
you ;
in prayer, as the Targum adds, this being a prayer gesture: notwithstanding his troubles continued and increased, he did not leave off praying, though he was not immediately heard and answered, which is what is tacitly complained of, as in (Psalms 22:2) . Christ, in his troubles in the garden, and on the cross, prayed for himself, for divine support and assistance, as man; for his friends, disciples, and apostles, and for all that should believe in him through them; and even for his enemies.
