Leviticus 25:52

And if but a little time be left of the years to the year of release, then shall he reckon to him according to his years, and shall pay his ransom

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.

If there remain but a few years to the year of jubilee, then he shall reckon with him; according to his years of service he shall give back the price of his redemption.
