Pretty sure the topic of this thread was the issue of Cherry Picking
I don't mind diving into more specific issues if that's your true intent, however. Let's start with slavery.
First off, slavery in general and throughout history does not equate to American Slavery, or slavery in similarly brutal cultures. American Slavery hinged upon racism and bigotry, where the enslaved were viewed as sub-humans (1/3 human to be exact) with no protections under the law. A white man could do whatever he wanted to with his slave: rape them, beat them, kill them, sell off their family, etc. A truly horrible, inhumane, greedy, and flat out evil practice.
The same cannot be said of slavery permitted under the Mosaic Law. In the first place, an slave wasn't viewed as sub-human or treated as a mere possession. They are people and have rights - indeed, are even treated as family.
Proverbs 29:21 He who pampers his slave from childhood Will in the end find him to be a son.
An Israeli servant was to be freed of his debts on the year of Jubilee (every 7 years), and go back to his life. If he had a wife or children, they would go free with him. Permanent slaves were permitted to be bought from among the surrounding pagan nations and the foreigners residing in the land.
Leviticus 25:39-46 “‘If any of your fellow Israelites become poor and sell themselves to you, do not make them work as slaves. 40 They are to be treated as hired workers or temporary residents among you; they are to work for you until the Year of Jubilee. 41 Then they and their children are to be released, and they will go back to their own clans and to the property of their ancestors. 42 Because the Israelites are my servants, whom I brought out of Egypt, they must not be sold as slaves. 43 Do not rule over them ruthlessly, but fear your God. 44 As for your male and female slaves whom you may have—you may acquire male and female slaves from the pagan nations that are around you. 45 Then, too,
it is out of the sons of the sojourners who live as aliens among you that you may gain acquisition, and out of their families who are with you, whom they will have aa]">[
aa]produced in your land; they also may become your possession. 46 You may even bequeath them to your sons after you, to receive as a possession; you can use them as permanent slaves. But in respect to your ab]">[
ab]countrymen, the sons of Israel, you shall not rule with severity over one another.
If a slave was killed by his/her master, the master would suffer vengeance:
Exodus 21:20 If a man strikes his male or female slave with a rod and he dies at his hand, he shall be punished (Literally: suffer vengeance).
If a slave is injured by his/her master, they were to be set free:
Exodus 21:26-27 “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. 27 And if he y]">[
y]knocks out a tooth of his male or female slave, he shall let him go free on account of his tooth.
If a slave runs away, he is not to be returned to his master - but is to be welcomed and treated with respect:
Deuteronomy 23:15-16 “You shall not hand over to his master a slave who has l]">[
l]escaped from his master to you. 16 He shall live with you in your midst, in the place which he shall choose in one of your m]">[
m]towns where it pleases him; you shall not mistreat him.
So then, when the scriptures speak of slaves and permitting people to be bought and sold - it is not the slavery which you are familiar with. The slavery permitted under the Mosaic Law is a humane one in which the individuals are still understood to be fellow men, and even family. Their mistreatment by their master nullifies their servitude - so the master was required to treat his slaves well if he were to keep them. Indeed, the slaves were even free to run away - and the Law required that they be welcomed by those they ran to and not returned to their master.
