Bits of Torah Truths – John the Baptist used the Torah to Rebuke Herod – Episode 18
יח כִּי יוֹחָנָן אָמַר לְהוֹרְדוֹס׃ אֵשֶׁת אָחִיךָ אֵינָהּ מֻתֶּרֶת לְךָ. (ויקרא יח׳ טז׳)
For John had said unto Herod, It is not lawful for thee to have thy brother’s wife. (KJV)
כא וְאִ֗ישׁ אֲשֶׁ֥ר יִקַּ֛ח אֶת־אֵ֥שֶׁת אָחִ֖יו נִדָּ֣ה הִ֑וא עֶרְוַ֥ת אָחִ֛יו גִּלָּ֖ה עֲרִירִ֥ים יִהְיֽוּ׃
And if a man shall take his brother’s wife, it is an unclean thing: he hath uncovered his brother’s nakedness; they shall be childless. (KJV)
Here John used Leviticus 20:21 regarding the command not to marry your brother’s wife. This suggests that the Torah is still valid today as much as it was when this book was written!
