Translations
And if you wonder in your heart, 'How can we know whether a word has truly come from Yahweh?'—
And if you say in your heart, 'How shall we know which word YHWH has not spoken?'—
And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?
You may ask in your heart, “How can we recognize a message that the LORD has not spoken?”
