Deuteronomy 15:10

“If you lend money to My people, to the afflicted among you, you are not to act as a creditor to him; you shall not charge him interest.

‘Now if a brother of yours becomes poor and his means with regard to you falter, then you are to sustain him, like a sojourner or a foreign resident, that he may live with you.

“And the Levite, because he has no portion or inheritance among you, and the sojourner, the orphan, and the widow who are within your gates, shall come and eat and be satisfied, in order that Yahweh your God may bless you in all the work of your hand which you do.

“You may charge interest to a foreigner, but to your brother you shall not charge interest, so that Yahweh your God may bless you in all that you send forth your hand to do in the land which you are about to enter to possess.

“You shall not oppress a hired person who is afflicted and needy, whether he is one of your brothers or one of your sojourners who is in your land within your gates.

“Yahweh will command the blessing upon you in your barns and in all that you send forth your hand to do, and He will bless you in the land which Yahweh your God gives you.

Cast your bread on the surface of the waters, for you will find it after many days.

“Give to him who asks of you, and do not turn away from him who wants to borrow from you.

Each one must do just as he has purposed in his heart, not grudgingly or under compulsion, for God loves a cheerful giver.
