Revelation 17:4 The woman was clothed in purple and scarlet, and adorned with gold and precious stones and pearls, having in her hand a gold cup full of abominations and of the unclean things of her immorality,

Revelation 21:12 It had a great and high wall, with twelve gates, and at the gates twelve angels; and names were written on them, which are the names of the twelve tribes of the sons of Israel.

Revelation 21:15 The one who spoke with me had a gold measuring rod to measure the city, and its gates and its wall.
