Jeremiah 27:9 Halakhah

וְ֠אַתֶּם אַל־תִּשְׁמְע֨וּ אֶל־נְבִיאֵיכֶ֜ם וְאֶל־קֹֽסְמֵיכֶ֗ם וְאֶל֙ חֲלֹמֹ֣תֵיכֶ֔ם וְאֶל־עֹֽנְנֵיכֶ֖ם וְאֶל־כַּשָּׁפֵיכֶ֑ם אֲשֶׁר־הֵ֞ם אֹמְרִ֤ים אֲלֵיכֶם֙ לֵאמֹ֔ר לֹ֥א תַעַבְד֖וּ אֶת־מֶ֥לֶךְ בָּבֶֽל׃

But as for you, hearken ye not to your prophets, nor to your diviners, nor to your dreams, nor to your soothsayers, nor to your sorcerers, that speak unto you, saying: Ye shall not serve the king of Babylon;
