John Gill Commentary 1 Kings 2:45

"But king Solomon shall be blessed, and the throne of David shall be established before Jehovah for ever." — 1 Kings 2:45 (ASV)

And King Solomon [shall be] blessed With a long and peaceable reign, and large dominions, notwithstanding all the attempts to make him unhappy:

and the throne of David shall be established before the Lord for ever ; the kingdom of David over Judah for a long time, in his natural line; and the kingdom of Israel, spiritual Israel, for ever in his son the Messiah; and that in the presence of the Lord, he observing, ordering, and succeeding all things to that purpose.
