This is the manner of the release: every creditor shall release that which he has lent to his neighbor; he shall not exact it of his neighbor and his brother; because the LORD's release has been proclaimed.
to a foreigner you may lend on interest; but to your brother you shall not lend on interest, that the LORD your God may bless you in all that you put your hand to, in the land where you go in to possess it.
When you shall vow a vow to the LORD your God, you shall not be slack to pay it: for the LORD your God will surely require it of you; and it would be sin in you.
