וְאַתֶּם֙ תָּשֻׁ֣בוּ הַיּ֔וֹם מֵאַחֲרֵ֖י יְהוָ֑ה וְהָיָ֗ה אַתֶּ֞ם תִּמְרְד֤וּ הַיּוֹם֙ בַּֽיהוָ֔ה וּמָחָ֕ר אֶֽל־כָּל־עֲדַ֥ת יִשְׂרָאֵ֖ל יִקְצֹֽף׃
that ye must turn away this day from following the LORD? and it will be, seeing ye rebel to-day against the LORD, that to-morrow He will be wroth with the whole congregation of Israel.
