Commenting on how slaves 'ought to be treated' doesn't exactly convey that slavery is wrong, does it? But since you wish to minimize the Bible condoning slavery, I'll remind you of Leviticus, Exodus, Ephesians, Timothy, or Luke:
"Slaves, obey your earthly masters with deep respect and fear."
"When a man sells his daughter as a slave, she will not be freed at the end of six years as the men are"
"However, you may purchase male or female slaves from among the foreigners who live among you. You may also purchase the children of such resident foreigners, including those who have been born in your land. You may treat them as your property, passing them on to your children as a permanent inheritance. You may treat your slaves like this, but the people of Israel, your relatives, must never be treated this way."
All of these passages (and others) were used by the pro-slavery crowd in our country to justify that institution. Hmm, using the Bible to justify immoral actions, now why does that sound familiar?
