וְשַׁעֲרֵ֣י הָעִ֗יר עַל־שְׁמוֹת֙ שִׁבְטֵ֣י יִשְׂרָאֵ֔ל שְׁעָרִ֥ים שְׁלוֹשָׁ֖ה צָפ֑וֹנָה שַׁ֣עַר רְאוּבֵ֞ן אֶחָ֗ד שַׁ֤עַר יְהוּדָה֙ אֶחָ֔ד שַׁ֥עַר לֵוִ֖י אֶחָֽד׃

Beginning on the north side, which will be 4,500 cubits long, the gates of the city will be named after the tribes of Israel. On the north side there will be three gates: the gate of Reuben, the gate of Judah, and the gate of Levi.
