Leviticus 25:35

32 Nevertheless the cities of the Levites, the houses of the cities of their possession, may the Levites redeem at any time.

33 If one of the Levites redeem, then the house that was sold, and the city of his possession, shall go out in the jubilee; for the houses of the cities of the Levites are their possession among the children of Israel.

34 But the field of the suburbs of their cities may not be sold; for it is their perpetual possession.

35 If your brother has grown poor, and his hand fail with you; then you shall uphold him: [as] a stranger and a sojourner shall he live with you.

36 Take no interest of him or increase, but fear your God; that your brother may live with you.

37 You shall not give him your money on interest, nor give him your victuals for increase.

38 I am Yahweh your God, who brought you forth out of the land of Egypt, to give you the land of Canaan, [and] to be your God.
