Deuteronomy 15:1-6

At the end of every seven years thou shalt make a release. And this is the manner of the release: every creditor shall release that which he hath lent unto his neighbor; he shall not exact it of his neighbor and his brother; because Jehovah’s release hath been proclaimed. Of a foreigner thou mayest exact it: but whatsoever of thine is with thy brother thy hand shall release. Howbeit there shall be no poor with thee (for Jehovah will surely bless thee in the land which Jehovah thy God giveth thee for an inheritance to possess it), if only thou diligently hearken unto the voice of Jehovah thy God, to observe to do all this commandment which I command thee this day. For Jehovah thy God will bless thee, as he promised thee: and thou shalt lend unto many nations, but thou shalt not borrow; and thou shalt rule over many nations, but they shall not rule over thee.
