Leviticus 25:51-53

Amplified Bible, Classic Edition

⁵¹ If there remain many years [before the Year of Jubilee], in proportion to them he must refund [to the purchaser] for his release [the overpayment] for his acquisition.

⁵² And if little time remains until the Year of Jubilee, he shall count it over with him and he shall refund the proportionate amount for his release.

⁵³ And as a servant hired year by year shall he deal with him; he shall not rule over him with harshness (severity, oppression) in your sight [make sure of that].
