Didache

Thou shalt not withhold thine hand from thy[*](Household duties) son or from thy daughter, but thou shalt teach them the fear of God from their youth up.

Thou shalt not command in thy bitterness thy slave or thine handmaid, who hope in the same God, lest they cease to fear the God who is over you both; for he comes not to call men with respect of persons, but those whom the Spirit has prepared.
