Deuteronomy 23:20-22

Revised Geneva Translation

²⁰ “You may lend with interest to a stranger. But you shall not lend with interest to your brother, so that the LORD your God may bless you in all that you set your hand to in the land to which you go to possess.

²¹ “When you shall vow a vow to the LORD your God, you shall not be slow to pay it. For the LORD your God will surely require it of you. And so it would be sin to you.

²² “But when you abstain from vowing, it shall be no sin to you.
