'Rash' in the Bible

“However, if she should marry while under her vows or the rash statement of her lips by which she has bound herself,

But if on the day her husband hears of it, he forbids her, then he shall annul her vow which she is under and the rash statement of her lips by which she has bound herself; and the Lord will forgive her.

“For then it would be heavier than the sand of the seas;Therefore my words have been rash.
