You may say in your heart, “How shall we know the word which Yahweh has not spoken?” When a prophet speaks in Yahweh’s name, if the thing doesn’t follow, nor happen, that is the thing which Yahweh has not spoken. The prophet has spoken it presumptuously. You shall not be afraid of him.
Therefore you are great, Yahweh God. For there is no one like you, neither is there any God besides you, according to all that we have heard with our ears.
