Néhémie 5:5
Yet now our flesh is as the flesh of our brethren, our children as their children: and, lo, we bring into bondage our sons and our daughters to be servants, and some of our daughters are brought unto bondage already: neither is it in our power to redeem them; for other men have our lands and vineyards.
Exode 21:2
If thou buy an Hebrew servant, six years he shall serve: and in the seventh he shall go out free for nothing.
Exode 21:3
If he came in by himself, he shall go out by himself: if he were married, then his wife shall go out with him.
