The word of the Lord came to Solomon - Some think that this is the same revelation as that mentioned 1-Kings 9:2, etc., which took place after the dedication of the temple: but to me it appears different; it was a word to encourage him while building; to warn him against apostasy, and to assure him of God's continued protection of him and his family, if they continued faithful to the grace which God had given.

And the word of the Lord came to Solomon,.... The word of prophecy, as the Targum, foretelling what would be the case of this building, according to the obedience or disobedience of him and the people of Israel; which was brought to him either by an impulse of the Spirit of God upon him; or by the hand of a prophet, as Kimchi thinks; and some of the Jewish writers (y), as he particularly, name Ahijah the Shilonite as the prophet that was sent with this message to him:
saying, as follows.
(y) Seder Olam Rabba, c. 20. p. 53.

None employ themselves for God, without having his eye upon them. But God plainly let Solomon know that all the charge for building this temple, would neither excuse from obedience to the law of God, nor shelter from his judgments, in case of disobedience.

GOD'S PROMISES UNTO IT. (1-Kings 6:11-14)
the word of the Lord came to Solomon--probably by a prophet. It was very seasonable, being designed: first, to encourage him to go on with the building, by confirming anew the promise made to his father David (2-Samuel 7:12-16); and secondly, to warn him against the pride and presumption of supposing that after the erection of so magnificent a temple, he and his people would always be sure of the presence and favor of God. The condition on which that blessing could alone be expected was expressly stated. The dwelling of God among the children of Israel refers to those symbols of His presence in the temple, which were the visible tokens of His spiritual relation to that people.

Promise of God during the Building of the Temple. - In what way this promise was communicated to Solomon is not more precisely stated. But the expression "And the word of Jehovah came" seems to point to a prophetic medium. And this is in harmony with 1-Kings 9:2, according to which Jehovah only revealed Himself to Solomon twice by an actual appearance.
