According to Bible history, ancient Mediterranean slavery and slavery in the United States were very different. The Old Testament has laws about the proper treatment of slaves. Exodus 21 is a good example. People became slaves in the ancient Mediterranean because of extreme poverty or debt. It was not because of skin color. However, in the United States, slavery was based on race. The United States did not allow slavery for the reason of hard times and survival the way ancient Mediterranean did. Ancient slavery had better reason than the United States.
