Devarim 18:18-20

Orthodox Jewish Bible

¹⁸ I will raise them up a Navi from among their achim, like unto thee, and will put My words in his mouth; and he shall speak unto them all that I shall command him [Yn 10:18].

¹⁹ And it shall come to pass, that whosoever will not listen unto My words which he shall speak Bishmi (in My Name), I will require it of him.

²⁰ But the navi, which shall presume to speak a word Bishmi (In My Name), which I have not commanded him to speak, or that shall speak in the shem of elohim acharim, even that navi shall die.
