Colossians 3:22
Slaves, obey your earthly masters in everything, not only while being watched and in order to please them, but wholeheartedly, fearing the Lord — the household code extends to slavery. 'Obey' (hypakouo) masters is commanded. 'Not only while watched' but 'wholeheartedly' (ex psyches) shows sincerity. 'Fearing the Lord' (phobos kyriou) reframes obedience: ultimate allegiance is Christ's. Slavery is unquestioned here, but submission is spiritualized.
