Revelation 21:12-17

ECB(i) 12 having a wall mega and high, having twelve gates, and at the gates twelve angels, and names epigraphed, being the twelve scions of the sons of Yisra El: 13 by the rising three gates; by the north three gates; by the south three gates; and by the lowering three gates. 14 And the wall of the city has twelve foundations and in them the names of the twelve apostles of the Lamb. 15
THE MEASUREMENTS OF THE NEW YERU SHALEM
And he speaking with me has a golden reed to measure the city and the gates and the wall: 16 and the city lies foursquare and the length is as long as the breadth: and he measures the city with the reed, twelve thousand stadia. The length and the breadth and the height are equal. 17 And he measures the wall a hundred and forty-four cubits - the measure of a human - being the angel.
