עַתָּ֕ה אַל־תַּקְשׁ֥וּ עָרְפְּכֶ֖ם כַּאֲבוֹתֵיכֶ֑ם תְּנוּ־יָ֣ד לַיהוָ֗ה וּבֹ֤אוּ לְמִקְדָּשׁוֹ֙ אֲשֶׁ֣ר הִקְדִּ֣ישׁ לְעוֹלָ֔ם וְעִבְדוּ֙ אֶת־יְהוָ֣ה אֱלֹהֵיכֶ֔ם וְיָשֹׁ֥ב מִכֶּ֖ם חֲר֥וֹן אַפּֽוֹ׃
Now be ye not stiffnecked, as your fathers were; but yield yourselves unto the LORD, and enter into His sanctuary, which He hath sanctified for ever, and serve the LORD your God, that His fierce anger may turn away from you.
