Deuteronomy 15:7–8

Do not harden your heart or close your hand to a brother in need

7If there is among you a needy one, one of your brothers, in one of your gates in your land that YHWH your Elohim is giving you, you shall not harden your heart or close your hand against your brother, the needy one.

8But you shall freely open your hand to him and freely lend him enough for his need, whatever he lacks.

In its context

5if only you truly obey the voice of YHWH your Elohim, being careful to carry out all this commandment that I am commanding you today.

6For YHWH your Elohim has blessed you, as he has spoken to you, and you will lend to many nations, but you will not borrow; and you will rule over many nations, but over you they will not rule.

…

9Guard yourself so that there is not a wicked word in your heart, saying, “The seventh year, the year of release, is near,” and your eye is evil toward your brother, the needy one, and you do not give him anything, and he cries out against you to YHWH, and it becomes sin in you.

10You shall freely give to him, and your heart shall not be grieved when you give to him, because on account of this thing YHWH your Elohim will bless you in all your work and in every undertaking of your hand.
