In the Bible, God says, "Slaves, obey your masters!"

Colossians 3:22

"Slaves, in all things obey those who are your masters on earth, not with external service, as those who merely please men"

1 Peter 2:18

"Servants, be submissive to your masters with all respect, not only to those who are good and gentle, but also to those who are unreasonable. 19For this finds favor, if for the sake of conscience toward God a person bears up under sorrows when suffering unjustly."

Why do you think that slavery in America lasted for so long? Yes, slavery was a big business but slave masters use the Bible to support slavery as the right thing to do.

Jesus myself mentioned slavery but he said to be kind to servants.

Apparently, the New Testament trumps the Old Testament, said the people who believed slavery was wrong.
