Deuteronomy 15:11

7If a poor man, one of your brothers, is with you within any of your gates in your land which the LORD your God gives you, you shall not harden your heart, nor shut your hand from your poor brother;

8but you shall surely open your hand to him, and shall surely lend him sufficient for his need, which he lacks.

9Beware that there not be a wicked thought in your heart, saying, “The seventh year, the year of release, is at hand,” and your eye be evil against your poor brother and you give him nothing; and he cry to the LORD against you, and it be sin to you.

10You shall surely give, and your heart shall not be grieved when you give to him, because it is for this thing the LORD your God will bless you in all your work and in all that you put your hand to.

11For the poor will never cease out of the land. Therefore I command you to surely open your hand to your brother, to your needy, and to your poor, in your land.

12If your brother, a Hebrew man, or a Hebrew woman, is sold to you and serves you six years, then in the seventh year you shall let him go free from you.

13When you let him go free from you, you shall not let him go empty.

14You shall furnish him liberally out of your flock, out of your threshing floor, and out of your wine press. As the LORD your God has blessed you, you shall give to him.

15You shall remember that you were a slave in the land of Egypt, and the LORD your God redeemed you. Therefore I command you this thing today.
