Leviticus 25:23

19And the land shall yield her fruit, and ye shall eat your fill, and dwell therein in safety.

20And if ye shall say, What shall we eat the seventh year? behold, we shall not sow, nor gather in our increase:

21Then I will command my blessing upon you in the sixth year, and it shall bring forth fruit for three years.

22And ye shall sow the eighth year, and eat yet of old fruit until the ninth year; until her fruits come in ye shall eat of the old store.

23The land shall not be sold for ever: for the land is mine; for ye are strangers and sojourners with me.

24And in all the land of your possession ye shall grant a redemption for the land.

25If thy brother be waxen poor, and hath sold away some of his possession, and if any of his kin come to redeem it, then shall he redeem that which his brother sold.

26And if the man have none to redeem it, and himself be able to redeem it;

27Then let him count the years of the sale thereof, and restore the overplus unto the man to whom he sold it; that he may return unto his possession.
