Revelation 21:14-16

New International Version

¹⁴ The wall of the city had twelve foundations,^(A) and on them were the names of the twelve apostles^(B) of the Lamb.

¹⁵ The angel who talked with me had a measuring rod^(C) of gold to measure the city, its gates^(D) and its walls. ¹⁶ The city was laid out like a square, as long as it was wide. He measured the city with the rod and found it to be 12,000 stadia^[a] in length, and as wide and high as it is long.
