'Void' in the Bible

and he shall dedicate himself to the Lord for the time of his separation and shall bring a male lamb a year old as a guilt offering; but the previous days will be void and lost, because his separation was defiled.

But if her husband disapproves of her [making her vow or pledge] on the day that he hears of it, then he shall annul her vow which she is under and the rash statement of her lips by which she bound herself; and the Lord will forgive her.

But if her husband absolutely annuls them on the day he heard them, then whatever proceeds from her lips concerning her vows or concerning her pledge shall not stand. Her husband has annulled them, and the Lord will forgive her.
