Neem 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.
Ex 21.2-3 If thou buy an Hebrew servant, six years he shall serve: and in the seventh he shall go out free for nothing.
