(3) The God of my rock.--In the psalm, "My God, my rock" (margin). The two expressions of the psalm are here united in one, and the recurrence of the similar expression in 2Samuel 22:47 (but not in the psalm) indicates that this was intentional.

And my refuge, my saviour; thou savest me from violence.--These words are omitted from the psalm, being compensated in part by the opening line there.

22:1-51 David's psalm of thanksgiving. - This chapter is a psalm of praise; we find it afterwards nearly as Ps 18. They that trust God in the way of duty, shall find him a present help in their greatest dangers: David did so. Remarkable preservations should be particularly mentioned in our praises. We shall never be delivered from all enemies till we get to heaven. God will preserve all his people, 2Ti 4:18. Those who receive signal mercies from God, ought to give him the glory. In the day that God delivered David, he sang this song. While the mercy is fresh, and we are most affected with it, let the thank-offering be brought, to be kindled with the fire of that affection. All his joys and hopes close, as all our hopes should do, in the great Redeemer.The God of my rock; in him will I:trust: he is my shield,

and the horn of my salvation, my high tower, and my refuge, my saviour;

thou savest me from violence. See Gill on Psalm 18:2.
