Deuteronomy 15:7

4 Save when there shall be no poor among you; for the LORD shall greatly bless thee in the land which the LORD thy God giveth thee [for] an inheritance to possess it:

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

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

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

8 But thou shalt open thine hand wide unto him, and shalt surely lend him sufficient for his need, [in that] which he wanteth.

9 Beware that there be not a thought in thy wicked heart, saying, The seventh year, the year of release, is at hand; and thine eye be evil against thy poor brother, and thou givest him nought; and he cry unto the LORD against thee, and it be sin unto thee.

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