Jeremiah 7:24 Halakhah

וְלֹ֤א שָֽׁמְעוּ֙ וְלֹֽא־הִטּ֣וּ אֶת־אָזְנָ֔ם וַיֵּֽלְכוּ֙ בְּמֹ֣עֵצ֔וֹת בִּשְׁרִר֖וּת לִבָּ֣ם הָרָ֑ע וַיִּהְי֥וּ לְאָח֖וֹר וְלֹ֥א לְפָנִֽים׃

But they hearkened not, nor inclined their ear, but walked in their own counsels, even in the stubbornness of their evil heart, and went backward and not forward,
