1 Peter 5:7 - Clarke's commentary and critical notes on the Bible

Casting all your care upon him; for he careth for you. Casting all your care - Την μεριμναν· Your anxiety, your distracting care, on him, for he careth for you, ὁτι αυτω μελει περι ὑμων, for he meddles or concerns himself, with the things that interest you. Whatever things concern a follower of God, whether they be spiritual or temporal, or whether in themselves great or small, God concerns himself with them; what affects them affects him; in all their afflictions he is afflicted. He who knows that God cares for him, need have no anxious cares about himself. This is a plain reference to Psalms 55:22 : Cast thy burden upon the Lord, and he will sustain thee. He will bear both thee and thy burden.
