Because our Creator requires us to treat everyone equally He includes in the covenant Exodus 21; 26—27,  “A man might hit his male or female slave in the eye. And the eye might be blinded. Then the man is to free the slave to pay for the eye. A master might knock out a tooth of his male or female slave. Then the man is to free the slave to pay for the tooth.” Servants may have belonged to someone but they were to be treated as equals and not as lesser people. We are all created in the image of our Creator, we should treat each other equally.
