Leviticus 25:23 (KJV)

Wherefore ye shall do my statutes, and keep my judgments, and do them; and ye shall dwell in the land in safety.

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

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

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

And 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.

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

If 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.

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

Then 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.

But if he be not able to restore it to him, then that which is sold shall remain in the hand of him that hath bought it until the year of jubile: and in the jubile it shall go out, and he shall return unto his possession.
