Leviticus 25:50-54

50The man and the person who bought him must count the time until the Jubilee year. The man must pay the right amount of money to be free.

51The Jubilee year may be many years away. If it is, the man must pay a lot of money to be free.

52There may be a few years until the Jubilee year. If there are, he has to pay only a small amount of money to be free.

53The person who has bought the man must pay him each year. You must cause the rich man to be kind to the man.

54Perhaps nobody will pay any money for the man. But the man who bought him must make him free in the Jubilee year.
