Deuteronomy 4:30 Halakhah

בַּצַּ֣ר לְךָ֔ וּמְצָא֕וּךָ כֹּ֖ל הַדְּבָרִ֣ים הָאֵ֑לֶּה בְּאַחֲרִית֙ הַיָּמִ֔ים וְשַׁבְתָּ֙ עַד־יְהוָ֣ה אֱלֹהֶ֔יךָ וְשָׁמַעְתָּ֖ בְּקֹלֽוֹ׃

In thy distress, when all these things are come upon thee, in the end of days, thou wilt return to the LORD thy God, and hearken unto His voice;
