Leviticus

But if he sanctify his field after the jubile, then the priest shall reckon unto him the money according to the years that remain, even unto the year of the jubile, and it shall be abated from thy estimation.

Then the priest shall reckon unto him the worth of thy estimation, even unto the year of the jubile: and he shall give thine estimation in that day, as a holy thing unto the Lord.

Let your moderation be known unto all men. The Lord is at hand.

And if a stranger shall sojourn among you, and will keep the passover unto the Lord; according to the ordinance of the passover, and according to the manner thereof, so shall he do: ye shall have one ordinance, both for the stranger, and for him that was born in the land.
