If he come in by himself, he shall go out by himself: if he be married, then his wife shall go out with him.
If thou buy a Hebrew servant, six years he shall serve: and in the seventh he shall go out free for nothing.
If his master give him a wife and she bear him sons or daughters; the wife and her children shall be her master's, and he shall go out by himself.
And if a man sell his daughter to be a maid-servant, she shall not go out as the men-servants do.
then shall he go out from thee, he and his children with him, and shall return unto his own family, and unto the possession of his fathers shall he return.
