It’s a simple thought repeated twice in this Psalm.
In God I Trust
Psa 56:1 To the chief Musician upon Jonathelemrechokim, Michtam of David, when the Philistines took him in Gath. Be merciful unto me, O God: for man would swallow me up; he fighting daily oppresseth me.
Psa 56:2 Mine enemies would daily swallow me up: for they be many that fight against me, O thou most High.

Psa 56:6 They gather themselves together, they hide themselves, they mark my steps, when they wait for my soul.

Psa 56:8 Thou tellest my wanderings: put thou my tears into thy bottle: are they not in thy book?
Psa 56:9 When I cry unto thee, then shall mine enemies turn back: this I know; for God is for me.
Psa 56:10 In God will I praise his word: in the LORD will I praise his word.
Psa 56:11 In God have I put my trust: I will not be afraid what man can do unto me.
Psa 56:12 Thy vows are upon me, O God: I will render praises unto thee.
Psa 56:13 For thou hast delivered my soul from death: wilt not thou deliver my feet from falling, that I may walk before God in the light of the living?
