All Israel — Not only the chief men, but a vast number of the common people. The feast — The feast of the dedication, to which Solomon had invited them. Seventh month — Which time he chose with respect to his peoples convenience, because now they had gathered in all their fruits, and were come up to Jerusalem, to celebrate the feast of tabernacles. But the temple was not finished till the eighth month, 1 Kings 6:38, how then could he invite them in the seventh month? This was the seventh month of the next year. For although the house in all its parts was finished the year before, yet the utensils of it were not then fully finished: and many preparations were to be made for this great and extraordinary occasion.
