לֹ֤א יָשׁוּב֙ אַף־יְהוָ֔ה עַד־עֲשֹׂת֥וֹ וְעַד־הֲקִימ֖וֹ מְזִמּ֣וֹת לִבּ֑וֹ בְּאַֽחֲרִית֙ הַיָּמִ֔ים תִּתְבּ֥וֹנְנוּ בָ֖הּ בִּינָֽה׃
The anger of the LORD shall not return, until He have executed, and till He have performed the purposes of His heart; in the end of days ye shall consider it perfectly.
Read halakhic rulings (Jewish law) on Jeremiah 23:20: and classical halakhic sources.
