It has been said by some that this Psalm is a prayer upon the 69th. It may be so taken. The title seems to mean, a Psalm "to put God in mind" - Messiah himself being the chief of God's Remembrancers.
v1: The cry
v2,3: First reason why the cry is heard: the guilt of his foes.
v4: Second reason why the cry is heard: the benefit of those who love the Lord
v5: Third reason why the cry his heard: his claims on God for deliverance from this state of humiliation and sorrow.
Thus the cry rises to heaven on the wings of three strong arguments certain to be answered in "the glory that was to follow" implied in the "help."
It is such a Psalm as every member of the Church has often had occasion to use, in sympathy with David, and in which he is sympathised with by the Son of David, whether asking present help or hastening to the day of his Coming, which brings full help and deliverance - "Wait not!"
But still, it is most of all Messiah whose voice is heard here. It may be called, with reference to Hebrews 5:7 One of the Righteous One's strong cries for speedy help.
