'Vow' in the Bible

You are to bring there your burnt offerings and sacrifices, your tenths and personal contributions, your vow offerings and freewill offerings, and the firstborn of your herds and flocks.

then Yahweh your God will choose the place to have His name dwell. Bring there everything I command you: your burnt offerings, sacrifices, offerings of the tenth, personal contributions, and all your choice offerings you vow to the Lord.

Within your gates you may not eat: the tenth of your grain, new wine, or oil; the firstborn of your herd or flock; any of your vow offerings that you pledge; your freewill offerings; or your personal contributions.

“But you are to take the holy offerings you have and your vow offerings and go to the place the Lord chooses.

Do not bring a female prostitute’s wages or a male prostitute’s earnings into the house of the Lord your God to fulfill any vow, because both are detestable to the Lord your God.

“If you make a vow to the Lord your God, do not be slow to keep it, because He will require it of you, and it will be counted against you as sin.

But if you refrain from making a vow, it will not be counted against you as sin.
