Concerning the issue of slavery:
"If a man strikes his male or female slave with a rod and he dies at his hand, he shall be punished. If, however, he survives a day or two, no vengeance shall be taken; for he is his property. If men struggle with each other and strike a woman with child so that she gives birth prematurely, yet there is no injury, he shall surely be fined as the woman’s husband may demand of him, and he shall pay as the judges decide. But if there is any further injury, then you shall appoint as a penalty life for life, eye for eye, tooth for tooth, hand for hand, foot for foot, burn for burn, wound for wound, bruise for bruise. If a man strikes the eye of his male or female slave, and destroys it, he shall let him go free on account of his eye. And if he knocks out a tooth of his male or female slave, he shall let him go free on account of his tooth."
-Exodus 21:20-27
"You shall not hand over to his master a slave who has escaped from his master to you. He shall live with you in your midst, in the place which he shall choose in one of your towns where it pleases him; you shall not mistreat him."
-Deuteronomy 23:15
A man shall be punished for killing a slave, and a slave shall be set free upon receiving grave injury. A man who strikes a woman with child shall also be punished as the circumstances demand. And an escaped slave shall not be returned to his master, and must not be mistreated in your care. This helps demonstrate the point I made earlier that while yes slavery exists, many of the brutal aspects of the instititution known at this time have been tamed by Biblical law.
