'Rash' in the Bible

And if she be married to a husband, while her vows are upon her, or the rash utterance of her lips, wherewith she hath bound her soul,

But if her husband disallow her in the day that he heareth it, then he shall make void her vow which is upon her, and the rash utterance of her lips, wherewith she hath bound her soul: and Jehovah will forgive her.
