Leviticus 25:50–52

He shall calculate with his buyer from the year when he sold himself to him until the year of jubilee, and the price of his sale shall vary with the number of years. The time he was with his owner shall be rated as the time of a hired worker. If there are still many years left, he shall pay proportionately for his redemption some of his sale price. If there remain but a few years until the year of jubilee, he shall calculate and pay for his redemption in proportion to his years of service.

They and their buyer are to count the time from the year they sold themselves up to the Year of Jubilee. The price for their release is to be based on the rate paid to a hired worker for that number of years. If many years remain, they must pay for their redemption a larger share of the price paid for them. If only a few years remain until the Year of Jubilee, they are to compute that and pay for their redemption accordingly.

The one who purchased him is to calculate the time from the year he sold himself to him until the Year of Jubilee. The price of his sale will be determined by the number of years. It will be set for him like the daily wages of a hired worker. If many years are still left, he must pay his redemption price in proportion to them based on his purchase price. If only a few years remain until the Year of Jubilee, he will calculate and pay the price of his redemption in proportion to his remaining years.

They will negotiate the price of their freedom with the person who bought them. The price will be based on the number of years from the time they were sold until the next Year of Jubilee—whatever it would cost to hire a worker for that period of time. If many years still remain until the jubilee, they will repay the proper proportion of what they received when they sold themselves. If only a few years remain until the Year of Jubilee, they will repay a small amount for their redemption.

And he shall calculate with his buyer from the year of his selling himself until the Jubilee; and the value of his selling shall be according to the number of years—it shall be with him like a hired worker’s days. If there are still many years, in keeping with them he shall restore his redemption in proportion to his purchase price. And if there are a few years left until the Year of Jubilee, then he shall calculate for himself; he shall restore his redemption according to the number of his years.

And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubile: and the price of his sale shall be according unto the number of years, according to the time of an hired servant shall it be with him. If there be yet many years behind, according unto them he shall give again the price of his redemption out of the money that he was bought for. And if there remain but few years unto the year of jubile, then he shall count with him, and according unto his years shall he give him again the price of his redemption.
