2 Chronicles 7:3 - Joseph Benson’s Commentary on the Old and New Testaments

The glory of the Lord upon the house The cloud first came down upon the house, and then entered into the house, and was seen both within it by the priests, and without it by the people; who by this evident token of the divine presence, and the sudden and miraculous descent of the fire, were fully satisfied that it was God's house, and that he would accept their sacrifices offered there, hear their prayers, and bestow his blessings upon them. They bowed themselves with their faces to the ground upon the pavement Fell prostrate upon the ground, thus expressing their awful dread of the divine majesty, their cheerful submission to the divine authority, and the sense they had of their utter unworthiness to enter into his presence. And worshipped and praised the Lord As they had great reason to do, having seen such manifest tokens of his presence among them. Saying, For he is good, &c. Thus using the same words in which the priests had just before praised him: a song never out of season, and for which our hearts and tongues should never be out of tune.
