Revelation 21:11-15

Revised Standard Version

¹¹ having the glory of God, its radiance like a most rare jewel, like a jasper, clear as crystal. ¹² It had a great, high wall, with twelve gates, and at the gates twelve angels, and on the gates the names of the twelve tribes of the sons of Israel were inscribed; ¹³ on the east three gates, on the north three gates, on the south three gates, and on the west three gates. ¹⁴ And the wall of the city had twelve foundations, and on them the twelve names of the twelve apostles of the Lamb.

¹⁵ And he who talked to me had a measuring rod of gold to measure the city and its gates and walls.
