1 Kings 8:66

On the eighth day he sent the people away
That is, of the feast of tabernacles, the eighth from the first of that, which was a solemn day, and fell on the twenty second of the month; at the close of which the dismission was made, or they had leave to go, but they did not until the twenty third, according to ( 2 Chronicles 7:10 )

and they blessed the king;
returned him thanks for his care, and charge, and pains, in building the temple; for prayers for them, and the feast he had now made, and wished all health and happiness to him:

and went unto their tents joyful and glad of heart;
or to their cities, as the Targum, to their several habitations; being greatly delighted with what they had seen and heard, and partook of especially:

for all the goodness the Lord had done for David his servant, and for
Israel his people;
in ( 2 Chronicles 7:10 ) , it is added, "unto Solomon"; for David, in giving him such a son and successor, who according to promise had built the house of the Lord; and for Solomon, in raising him up to such dignity, and enabling him to build such a temple for the worship of God and his glory; and for the people of Israel, in giving them such a king to rule over them, under whom they enjoyed so much peace and prosperity, and the full and free exercise of the true religion, with such accommodations, and in such a splendid manner as now.
