Treasure Cities

Boyd’s Bible Dictionary:

The kings of Judah, and of other nations, kept their treasures in designated cities, called treasure-cities, and in special buildings called treasure-houses

(Ex. 1:11¹¹Therefore they did set over them taskmasters to afflict them with their burdens. And they built for Pharaoh treasure cities, Pithom and Raamses. (Exodus 1:11); 1 Chron. 27:25²⁵And over the king's treasures was Azmaveth the son of Adiel: and over the storehouses in the fields, in the cities, and in the villages, and in the castles, was Jehonathan the son of Uzziah: (1 Chronicles 27:25); Ezra 5:17¹⁷Now therefore, if it seem good to the king, let there be search made in the king's treasure house, which is there at Babylon, whether it be so, that a decree was made of Cyrus the king to build this house of God at Jerusalem, and let the king send his pleasure to us concerning this matter. (Ezra 5:17)).
