1 Kings 8:14 - Matthew Poole's English Annotations on the Holy Bible

The king turned his face about, from the temple, towards which he was looking to observe that thick and extraordinary darkness, to the body of the congregation. Blessed all the congregation of Israel, or, blessed (to wit, the Lord, which is easily understood from the following words; in which he only blesseth or praiseth God, but doth not bless the people at all) with (so the Hebrew eth is oft used, as hath been showed before) all the congregation. Although he might do both, first bless the congregation, which possibly he might do in that solemn and appointed form, Num 6; which therefore it was needless to repeat here; and then blessed God. And indeed he doth both here below, where these same words are used, 1 Kings 8:55,56, &c. The congregation of Israel stood; partly in way of devotion to God, whom they adored; and partly out of respect to the king.
