Commentary for Jeremiah 4:4

הִמֹּ֣לוּ לַיהֹוָ֗ה וְהָסִ֙רוּ֙ עָרְל֣וֹת לְבַבְכֶ֔ם אִ֥ישׁ יְהוּדָ֖ה וְיֹשְׁבֵ֣י יְרוּשָׁלִָ֑ם פֶּן־תֵּצֵ֨א כָאֵ֜שׁ חֲמָתִ֗י וּבָעֲרָה֙ וְאֵ֣ין מְכַבֶּ֔ה מִפְּנֵ֖י רֹ֥עַ מַעַלְלֵיכֶֽם׃

Circumcise yourselves to the LORD, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem; lest My fury go forth like fire, and burn that none can quench it, Because of the evil of your doings.
