The names of the 12 tribes of Israel were written on the gates. ¹³There were three gates on the east, three gates on the north, three gates on the south, and three gates on the west. ¹⁴The wall of the city had 12 foundations. The 12 names of the 12 apostles of the lamb were written on them. 

¹⁵The angel who was talking to me had a gold measuring stick to measure the city, its gates, and its wall. ¹⁶The city was square. It was as wide as it was long. He measured the city with the stick. It was 12,000 stadia^blong. Its length, width, and height were the same. ¹⁷He measured its wall. According to human measurement, which the angel was using, it was 144 cubits.^c18Its wall was made of gray quartz. The city was made of pure gold, as clear as glass. ¹⁹The foundations of the city wall were beautifully decorated with all kinds of gems: The first foundation was gray quartz, the second sapphire, the third agate, the fourth emerald, ²⁰the fifth onyx, the sixth red quartz, the seventh yellow quartz, the eighth beryl, the ninth topaz, the tenth green quartz, the eleventh jacinth, and the twelfth amethyst. ²¹The 12 gates were 12 pearls.
