The Sons of Israel, You Shall Not Rule Over One Another With Harshness

You may buy male and female slaves from among the nations that are round about you. And they may be your property, to inherit as a possession forever. You shall not rule over him with harshness, but shall fear your god. The price of his release shall be according to the number of years the time he was with his owner Shall be rated as the time of a hired servant. Psalm 81: "I am the lord your god"
