וּ֠רְגָמֻהוּ כָּל־אַנְשֵׁ֨י עִיר֤וֹ בָֽאֲבָנִים֙ וָמֵ֔ת וּבִֽעַרְתָּ֥ הָרָ֖ע מִקִּרְבֶּ֑ךָ וְכָל־יִשְׂרָאֵ֖ל יִשְׁמְע֥וּ וְיִרָֽאוּ׃ (ס)

And all the men of his city shall stone him with stones, that he die; so shalt thou put away the evil from the midst of thee; and all Israel shall hear, and fear.
