Matthew 5:33
Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto Yahweh thine oaths
Deuteronomy 23:21-23
When thou shalt vow a vow unto the Yahweh thy God, thou shalt not slack to pay it: for Yahweh thy God will surely require it of thee; and it would be sin in thee.
But if thou shalt forbear to vow, it shall be no sin in thee.
That which is gone out of thy lips thou shalt keep and perform; even a freewill offering, according as thou hast vowed unto Yahweh thy God, which thou hast promised with thy mouth.
