Leviticus 24:22
Ye shall have one manner of law, as well for the stranger, as for one of your own country: for I am the LORD your God. Ye shall have one manner of law, as well for the stranger, as for one of your own country: for I am the LORD your God.
There is one manner of law, holding the same for the stranger as for one born in the country. When a person falls into poverty, that equal standing requires active relief for the poor, expressly including the stranger and sojourner. The same equality forbids charging them interest on help given or demanding any additional payment beyond what is fair.
