Jamieson, Fausset and Brown on 1 Peter 5:7

7. Casting--once for all: so the Greek aorist.

care--"anxiety? The advantage flowing from humbling ourselves under God's hand (1Pe 5:6) is confident reliance on His goodness. Exemption from care goes along with humble submission to God.

careth for you--literally "respecting you." Care is a burden which faith casts off the man on his God. Compare Psa 22:10; 37:5; 55:22, to which Peter alludes; Lu 12:22, 37; Php 4:6.

careth--not so strong a Greek word as the previous Greek "anxiety."
