'Vowed' in the Bible
Speak unto the children of Israel, and say unto them, If a man or a woman have vowed the special vow of a Nazarite, to consecrate themselves to Jehovah;
This is the law of the Nazarite who hath vowed, and of his offering unto the LORD for his separation, beside that that his hand shall get: according to the vow which he vowed, so he must do after the law of his separation.
Every devoted thing in Israel [everything that has been promised to the Lord with an oath] shall be yours.
And Israel vowed a vow unto the LORD, and said, If thou wilt indeed deliver this people into my hand, then I will utterly destroy their cities.
‘You shall present these to the Lord at your appointed times, in addition the offerings you have vowed and your freewill offerings, as your burnt offerings, grain offerings, drink offerings, and as your peace offerings.’”
And if she had at all an husband, when she vowed, or uttered ought out of her lips, wherewith she bound her soul;
But if her husband disallowed her on the day that he heard it; then he shall make her vow which she vowed, and that which she uttered with her lips, wherewith she bound her soul, of none effect: and the LORD shall forgive her.
