Revelation 21:12,13

And had a wall great and high... — Or, better (for the construction is continued), Having a wall great and high, and having twelve gate-towers, and at the gate-towers twelve angels, and names inscribed which are (names) of the twelve tribes of the sons of Israel: from the sun-rising (i.e., facing east) three gate-towers; from the north three gate-towers, from the south three gate-towers; from the sun-setting three gate-towers. On this arrangement of gates Numbers 2; Ezekiel 48, and Revelation 7 should be compared. In the encampment in the wilderness (Numbers 2) the tribes were arranged as follows: on the east, Judah, Issachar, Zebulun; on the south, Reuben, Simeon, Gad; on the west, Ephraim, Manasseh, Benjamin; on the north, Dan, Asher, Naphtali. There is perhaps allusion in the present passage to this wilderness encampment, and to the re-adjustment of the order of the tribes in Ezekiel (Ezekiel 48); but there is more than order here: the gates lie open to all quarters; there is no refusal of admission to any people. The representatives of all nations, and kindreds, and people, and tongues, are (Revelation 7:9) in the city of Christ; in Him there is neither barbarian, Scythian, bond nor free, but all are one. The diversities of human nationality and character, of age and race, and climate, are brought into one communion and fellowship. (Comp. Note on Revelation 7:4.) “The wall great and high” is mentioned to assure us of the security and peace of that city where no foe “or thief approacheth” (Isaiah 26:1; Zechariah 2:5).
