Deuteronomy Chapter 15

15:1-2
At the end of every seven years thou shalt make a release.
And this is the manner of the release: Every creditor that lendeth aught unto his neighbour shall release it; he shall not exact it of his neighbour, or of his brother; because it is called the Lord's release.

15:6
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.

15:9-11
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.
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.
For the poor shall never cease out of the land: therefore I command thee, saying, Thou shalt open thine hand wide unto thy brother, to thy poor, and to thy needy, in thy land.
