Ezekiel 48:30-34

There are twelve entrances to the city of Jerusalem. Each of the four walls measures 2,250 metres and has three gates in it, each named after one of the tribes. The gates in the north wall are named after Reuben, Judah, and Levi; those in the east wall, after Joseph, Benjamin, and Dan; those in the south wall, after Simeon, Issachar, and Zebulun; and those in the west wall are named after Gad, Asher, and Naphtali.
