Commentary for Jeremiah 3:18

בַּיָּמִ֣ים הָהֵ֔מָּה יֵלְכ֥וּ בֵית־יְהוּדָ֖ה עַל־בֵּ֣ית יִשְׂרָאֵ֑ל וְיָבֹ֤אוּ יַחְדָּו֙ מֵאֶ֣רֶץ צָפ֔וֹן עַל־הָאָ֕רֶץ אֲשֶׁ֥ר הִנְחַ֖לְתִּי אֶת־אֲבוֹתֵיכֶֽם׃

In those days the house of Judah shall walk with the house of Israel, and they shall come together out of the land of the north to the land that I have given for an inheritance unto your fathers.’

Rashi on Jeremiah
