Commentary for Jeremiah 19:4

יַ֣עַן ׀ אֲשֶׁ֣ר עֲזָבֻ֗נִי וַֽיְנַכְּר֞וּ אֶת־הַמָּק֤וֹם הַזֶּה֙ וַיְקַטְּרוּ־בוֹ֙ לֵאלֹהִ֣ים אֲחֵרִ֔ים אֲשֶׁ֧ר לֹֽא־יְדָע֛וּם הֵ֥מָּה וַאֲבֽוֹתֵיהֶ֖ם וּמַלְכֵ֣י יְהוּדָ֑ה וּמָֽלְא֛וּ אֶת־הַמָּק֥וֹם הַזֶּ֖ה דַּ֥ם נְקִיִּֽם׃

because they have forsaken Me, and have estranged this place, and have offered in it unto other gods, whom neither they nor their fathers have known, nor the kings of Judah; and have filled this place with the blood of innocents;
