Jeremiah 7:16 Halakhah

וְאַתָּ֞ה אַל־תִּתְפַּלֵּ֣ל ׀ בְּעַד־הָעָ֣ם הַזֶּ֗ה וְאַל־תִּשָּׂ֧א בַעֲדָ֛ם רִנָּ֥ה וּתְפִלָּ֖ה וְאַל־תִּפְגַּע־בִּ֑י כִּי־אֵינֶ֥נִּי שֹׁמֵ֖עַ אֹתָֽךְ׃

Therefore pray not thou for this people, neither lift up cry nor prayer for them, neither make intercession to Me; for I will not hear thee.
