Deuteronomy 15:5-10

5Only if thou shalt carefully hearken to the voice of the LORD thy God, to observe to do all these commandments which I command thee this day.

6For the LORD thy God shall bless thee, as he promised thee: and thou shalt lend to many nations, but thou shalt not borrow; and thou shalt reign over many nations, but they shall not reign over thee.

7If there shall be among you a poor man of one of thy brethren within any of thy gates in thy land which the LORD the God giveth thee, thou shalt not harden thy heart, nor shut thy hand from thy poor brother:

8But thou shalt open thy hand wide to him, and shalt surely lend him sufficient for his need, in that which he lacketh.

9Beware that there be not a thought in thy wicked heart, saying, The seventh year, the year of release, is at hand; and thy eye shall be evil against thy poor brother, and thou shalt give him nothing; and he shall cry to the LORD against thee, and it shall be sin to thee.12

10Thou shalt surely give him, and thy heart shall not be grieved when thou givest to him: because that for this thing the LORD thy God shall bless thee in all thy works, and in all that thou puttest thy hand to.
