Leviticus 25:36

32 As for the cities of the Levites, the Levites always have the right to redeem their houses in the cities they possess.

33 So whatever belongs to the Levites may be redeemed—a house sold in a city they possess—and must be released in the Jubilee, because the houses in the cities of the Levites are their possession among the Israelites.

34 But the open pastureland around their cities may not be sold, for this is their permanent possession.

35 Now if your countryman becomes destitute and cannot support himself among you, then you are to help him as you would a foreigner or stranger, so that he can continue to live among you.

36 Do not take any interest or profit from him, but fear your God, that your countryman may live among you.

37 You must not lend him your silver at interest or sell him your food for profit.

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

39 If a countryman among you becomes destitute and sells himself to you, then you must not force him into slave labor.

40 Let him stay with you as a hired worker or temporary resident; he is to work for you until the Year of Jubilee.
