וְהָאִ֞ישׁ אֲשֶׁר־יַעֲשֶׂ֣ה בְזָד֗וֹן לְבִלְתִּ֨י שְׁמֹ֤עַ אֶל־הַכֹּהֵן֙ הָעֹמֵ֞ד לְשָׁ֤רֶת שָׁם֙ אֶת־יְהוָ֣ה אֱלֹהֶ֔יךָ א֖וֹ אֶל־הַשֹּׁפֵ֑ט וּמֵת֙ הָאִ֣ישׁ הַה֔וּא וּבִֽעַרְתָּ֥ הָרָ֖ע מִיִּשְׂרָאֵֽל׃
And the man that doeth presumptuously, in not hearkening unto the priest that standeth to minister there before the LORD thy God, or unto the judge, even that man shall die; and thou shalt exterminate the evil from Israel.
