Deuteronomy 15:6

3 A man of another nation may be forced to make payment of his debt, but if your brother has anything of yours, let it go;

4 But there will be no poor among you; for the Lord will certainly give you his blessing in the land which the Lord your God is giving you for your heritage;

5 If only you give ear to the voice of the Lord your God, and take care to keep all these orders which I give you today.

6 For the Lord your God will give you his blessing as he has said: you will let other nations have the use of your money, but you will not make use of theirs; you will be rulers over a number of nations, but they will not be your rulers.

7 If in any of your towns in the land which the Lord your God is giving you, there is a poor man, one of your countrymen, do not let your heart be hard or your hand shut to him;

8 But let your hand be open to give him the use of whatever he is in need of.

9 And see that there is no evil thought in your heart, moving you to say to yourself, The seventh year, the year of forgiveness is near; and so looking coldly on your poor countryman you give him nothing; and he will make an outcry to the Lord against you, and it will be judged as sin in you.
