Exodus 21:11

And if he do not these three unto her, that is, if, in the three given instances, he does not do the right thing by her, then shall she go out free without money. The woman would have her freedom, and her father would have the advantage of the purchase-money. Thus was the Hebrew male or female servant protected, for the Israelites were not to forget that the lowly among their people were likewise members of God's chosen nation. The principle applies to Christian masters also, inasmuch as they will treat even the least among the believers as brethren and sisters in Christ.
