Psalm 73:21-23, 26
Psalm 73:21-23 ESV
When my soul was embittered, when I was pricked in heart, I was brutish and ignorant; I was like a beast toward you. Nevertheless, I am continually with you; you hold my right hand.

My flesh and my heart may fail, but God is the strength of my heart and my portion forever.
