Adam Clarke on 1 Chronicles 28:11

David gave to Solomon - the pattern - He gave him an ichnograph of the building, with elevations, sections, and specifications of every part; and all this he received by inspiration from God himself, (see 1Chr 28:12, 1Chr 28:19), just as Moses had received the plan of the tabernacle.

The treasuries thereof - גנזכיו ganzaccaiv. The word גנזך ganzach is not Hebrew, but is supposed to be Persian, the same word being found in Ezr 3:1-13 :19. In this tongue we have the word ganj, a granary, a hidden treasure, and gunjoor, and gunjineh, a treasure, treasury, or barn. Parkhurst supposes that it is compounded of גנז ganaz, to treasure up, and זך zach, pure; a treasury for the most precious things.
