Exodus 21:3-5 Easy-to-Read Version (ERV)
3 If he is not married when he becomes your slave, when he becomes free, he will leave without a wife. But if the man is married when he becomes your slave, then he will keep his wife at the time he is made free. 4 If the slave is not married, the master can give him a wife. If that wife gives birth to sons or daughters, she and her children will belong to the master. After the slave is finished with his years of service, he will be made free.
5 “But if the slave decides that he wants to stay with the master, he must say, ‘I love my master. I love my wife and my children. I will not become free—I will stay.’
