Psalm Seventy
by Dr. Henry M. Morris
(taken from the Defender's Study Bible)
To the chief Musician, A Psalm of David, to bring to remembrance.
Psalm 70:1 Make haste, O God, to deliver me; make haste to help me, O LORD.
make haste. The five verses of this psalm are practically identical to the last five verses of Psalm 40. Psalm 40 was a Messianic psalm and so is Psalm 70. Perhaps David was led to tie them both together in this way to emphasize their anticipation of the suffering Messiah.
Psalm 70:3 Let them be turned back for a reward of their shame that say, Aha, aha.
