Leviticus 25:33-37

And if a man purchase of the Levites, then the house that was sold, and the city of his possession, shall go out in the year of jubile: for the houses of the cities of the Levites are their possession among the children of Israel.

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

And if thy brother be waxen poor, and fallen in decay with thee; then thou shalt relieve him: yea, though he be a stranger, or a sojourner; that he may live with thee.

Take thou no usury of him, or increase: but fear thy God; that thy brother may live with thee.

Thou shalt not give him thy money upon usury, nor lend him thy victuals for increase.
Leviticus 25:33-37
