Commentary for Jeremiah 31:9

בִּבְכִ֣י יָבֹ֗אוּ וּֽבְתַחֲנוּנִים֮ אֽוֹבִילֵם֒ אֽוֹלִיכֵם֙ אֶל־נַ֣חֲלֵי מַ֔יִם בְּדֶ֣רֶךְ יָשָׁ֔ר לֹ֥א יִכָּשְׁל֖וּ בָּ֑הּ כִּֽי־הָיִ֤יתִי לְיִשְׂרָאֵל֙ לְאָ֔ב וְאֶפְרַ֖יִם בְּכֹ֥רִי הֽוּא׃ (ס)

They shall come with weeping, And with supplications will I lead them; I will cause them to walk by rivers of waters, In a straight way wherein they shall not stumble; For I am become a father to Israel, And Ephraim is My first-born.
