Exodus 21:3-5

Contemporary English Version

³ If he was single at the time you bought him, he alone must be set free. But if he was married at the time, both he and his wife must be given their freedom. ⁴ If you give him a wife, and they have children, only the man himself must be set free; his wife and children remain the property of his owner.

⁵ But suppose the slave loves his wife and children and his owner so much that he won't leave them.
