Deuteronomy 15:10

If 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;

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

Beware 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.

For 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.

If 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.

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