Leviticus 25:26-36

26 and when a man hath no redeemer, and his own hand hath attained, and he hath found as sufficient [for] its redemption,
27 then he hath reckoned the years of its sale, and hath given back that which is over to the man to whom he sold [it], and he hath returned to his possession.
28 `And if his hand hath not found sufficiency to give back to him, then hath his sold thing been in the hand of him who buyeth it till the year of jubilee; and it hath gone out in the jubilee, and he hath returned to his possession.
29 `And when a man selleth a dwelling-house [in] a walled city, then hath his right of redemption been until the completion of a year from its selling; days -- is his right of redemption;
30 and if it is not redeemed until the fulness to him of a perfect year, then hath the house which [is] in a walled city been established to extinction to the buyer of it, to his generations; it goeth not out in the jubilee;
31 and a house of the villages which have no wall round about, on the field of the country is reckoned; redemption is to it, and in the jubilee it goeth out.
32 `As to cities of the Levites -- houses of the cities of their possession -- redemption age-during is to the Levites;
33 as to him who redeemeth from the Levites, both the sale of a house and the city of his possession have gone out in the jubilee, for the houses of the cities of the Levites are their possession in the midst of the sons of Israel.
34 And a field, a suburb of their cities, is not sold; for a possession age-during it [is] to them.
35 `And when thy brother is become poor, and his hand hath failed with thee, then thou hast kept hold on him, sojourner and settler, and he hath lived with thee;
36 thou takest no usury from him, or increase; and thou hast been afraid of thy God; and thy brother hath lived with thee;
