1 Peter 5:7

This verse does not introduce a new command but explains how to humble oneself: by entrusting oneself and one’s troubles to God (Psalms 55:22; cf. Matthew 6:25-34; Philippians 4:6). We can do this because we have confidence that God cares for our welfare.

"Mermina [sic, merimna] = worry or anxiety as when one does not know whether to do this or to do that, ’distraction.’" [Note: Lenski, p. 224. Cf. Psalms 55:22; 37:5; Luke 10:41; 12:11-12.]
