1 Kings 7:3

Andit was covered with cedar above upon the beams The word here rendered -beams" is the same which has been rendered -side-chambers" in 1 Kings 6:5. In two descriptions which are so closely related as that chapter and this, it is difficult to suppose that the word has a different sense in the two places. And we have here an account of a series of side-chambers which ran all round the inside walls of this house of the forest of Lebanon, as the others did round the outside wall of the Temple. Taking the word as = -side-chambers," the text says that they were supported upon the pillars already mentioned in 1 Kings 7:2, and then adds that these chambers were forty-five in number, fifteen in a row. This seems to mean that the whole three tiers of rooms numbered forty-five, each of the three stories being divided into fifteen chambers. If we suppose that the chambers were only on three sides like those surrounding the Temple, then six on each side and three at each end would exactly make up the number, and would suit with the dimensions of the house, which was twice as long as it was broad. The whole verse then may be translated -And it was covered with cedar above, over the forty and five side-chambers, which were upon the pillars, fifteen in a row."
