See, I have taught you statutes and rules, as the LORD my God commanded me, that you should do them in the land that you are entering to take possession of it. Keep them and do them, for that will be your wisdom and your understanding in the sight of the peoples, who, when they hear all these statutes, will say, ‘Surely this great nation is a wise and understanding people.’ For what great nation is there that has a god so near to it as the LORD our God is to us, whenever we call upon him? And what great nation is there, that has statutes and rules so righteous as all this law that I set before you today?

“At the end of every seven years you shall grant a release. And this is the manner of the release: every creditor shall release what he has lent to his neighbor. He shall not exact it of his neighbor, his brother, because the LORD's release has been proclaimed. Of a foreigner you may exact it, but whatever of yours is with your brother your hand shall release. But there will be no poor among you; for the LORD will bless you in the land that the LORD your God is giving you for an inheritance to possess—if only you will strictly obey the voice of the LORD your God, being careful to do all this commandment that I command you today. For the LORD your God will bless you, as he promised you, and you shall lend to many nations, but you shall not borrow, and you shall rule over many nations, but they shall not rule over you.

“If among you, one of your brothers should become poor, in any of your towns within your land that the LORD your God is giving you, you shall not harden your heart or shut your hand against your poor brother, but you shall open your hand to him and lend him sufficient for his need, whatever it may be. Take care lest there be an unworthy thought in your heart and you say, ‘The seventh year, the year of release is near,’ and your eye look grudgingly on your poor brother, and you give him nothing, and he cry to the LORD against you, and you be guilty of sin. You shall give to him freely, and your heart shall not be grudging when you give to him, because for this the LORD your God will bless you in all your work and in all that you undertake. For there will never cease to be poor in the land. Therefore I command you, ‘You shall open wide your hand to your brother, to the needy and to the poor, in your land.’

(Deuteronomy 4:5-8; 15:1-11 ESV)
