And this is the manner of the release: Every creditor that lends ought to his neighbor shall release it; he shall not exact it of his neighbor, or of his brother; because it is called the LORD's release.
To a stranger you may lend on usury; but to your brother you shall not lend on usury: that the LORD your God may bless you in all that you set your hand to in the land where you go to possess it.
When you shall vow a vow to the LORD your God, you shall not slack to pay it: for the LORD your God will surely require it of you; and it would be sin in you.
