Kara means to bow down, kneel, or fall prostrate. It appears about 36 times. It describes kneeling in worship before God, in submission before a king, or in collapse before an enemy.
Bowing expresses the posture of worship and submission God deserves. 'Every knee will bow' (Isaiah 45:23, Philippians 2:10). Kara represents the physical embodiment of spiritual surrender — acknowledging God's authority with one's whole being.
