'Master' in the Bible

If his master gives him a wife and she bears him sons or daughters, the wife and her children shall be her master's, and he shall go out by himself.

But if the servant shall plainly say, 'I love my master, my wife, and my children. I will not go out free;'

then his master shall bring him to God, and shall bring him to the door or to the doorpost, and his master shall bore his ear through with an awl, and he shall serve him for ever.

If she doesn't please her master, who has married her to himself, then he shall let her be redeemed. He shall have no right to sell her to a foreign people, since he has dealt deceitfully with her.

If the bull gores a male servant or a female servant, thirty shekels of silver shall be given to their master, and the ox shall be stoned.

If the thief isn't found, then the master of the house shall come near to God, to find out if he hasn't put his hand to his neighbor's goods.
