NASB
""You may say in your heart, 'How will we know the word which the LORD has not spoken?'"
— Deuteronomy 18:21, NASB
“And if thou say in thine heart, How shall we know the word which the Lord hath not spoken?”
“And if thou say in thy heart, How shall we know the word which Jehovah hath not spoken? ”
“If you say in your heart, "How shall we know the word which Yahweh has not spoken?"”
“Now if you say to yourselves,‘How can we tell that a message is not from the LORD?’–”
“And if in silent thought thou answer: How shall I know the word that the Lord hath not spoken?”
“And if you say in your hearts, How are we to be certain that the word does not come from the Lord?”
“And if thou say in thine heart, How shall we know the word which the Lord hath not spoken?”
'I will raise up a prophet from among their countrymen like you, and I will put My words in his mouth, and he shall speak to them all that I command him.
'It shall come about that whoever will not listen to My words which he shall speak in My name, I Myself will require it of him.
'But the prophet who speaks a word presumptuously in My name which I have not commanded him to speak, or which he speaks in the name of other gods, that prophet shall die.'
"You may say in your heart, 'How will we know the word which the LORD has not spoken?'
"When a prophet speaks in the name of the LORD, if the thing does not come about or come true, that is the thing which the LORD has not spoken. The prophet has spoken it presumptuously; you shall not be afraid of him.
