'Vow' in the Bible

then it shall come to pass that to the place which Jehovah your God shall choose, to cause his name to dwell there, thither shall ye bring all that I command you: your burnt-offerings, and your sacrifices, your tithes, and the heave-offering of your hand, and all your choice vows which ye vow unto Jehovah.

Thou shalt not bring the hire of a harlot, or the wages of a dog, into the house of Jehovah thy God for any vow: for even both these are an abomination unto Jehovah thy God.

When thou shalt vow a vow unto Jehovah thy God, thou shalt not be slack to pay it: for Jehovah 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.
