When you make a vow to the LORD your God, don't put off fulfilling it. The LORD your God will hold you to it, and failing to keep it would be sin.
When thou shalt vow a vow unto the LORD thy God, thou shalt not slack to pay it: for the LORD thy God will surely require it of thee; and it would be sin in thee.
