Psalms 56:9

7 Shall they escape by iniquity? in thine anger cast down the people, O God.

8 Thou tellest my wanderings: put thou my tears into thy bottle: are they not in thy book?

When I cry unto thee, then shall mine enemies turn back: this I know; for God is for me.

10 In God will I praise his word: in the LORD will I praise his word.

11 In God have I put my trust: I will not be afraid what man can do unto me.

Do read the surrounding verses too, because the context often says more than a single verse.
