Now when Hiram had heard the words of Solomon, he rejoiced exceedingly, and said: Blessed be the Lord God this day, who hath given to David a very wise son over this numerous people.

And it cometh to pass at Hiram's hearing the words of Solomon, that he rejoiceth exceedingly, and saith, 'Blessed is Jehovah to-day, who hath given to David a wise son over this numerous people.'

And these words of Solomon made Hiram glad, and he said, Now may the Lord be praised who has given to David a wise son to be king over this great people.

Therefore, when Hiram had heard the words of Solomon, he rejoiced greatly, and he said, "Blessed be the Lord God this day, who gave to David a very wise son over this numerous people!"

Blessed be the Lord this day - From this, and indeed from every part of Hiram's conduct, it is evident that he was a worshipper of the true God; unless, as was the case with many of the heathens, he supposed that every country had its own god, and every god his own country, and he thanked the God of Israel that he had given so wise a prince to govern those whom he considered his friends and allies: but the first opinion seems to be the most correct.

And it came to pass, when (c) Hiram heard the words of Solomon, that he rejoiced greatly, and said, Blessed [be] the LORD this day, which hath given unto David a wise son over this great people.
(c) In Hiram is prefigured the calling of the Gentiles who would help build the spiritual temple.

And it came to pass, when Hiram heard the words of Solomon,.... The letter read he sent him:
that he rejoiced greatly; that the friendship which had subsisted between him and David was like to be continued between him and his successor, but chiefly for what follows:
saying, blessed be the Lord this day; or Jehovah, by which he seems to have some knowledge of the true God, the God of Israel, and might worship him, though along with him other deities, as some Heathen princes did:
which hath given unto David a wise son over this great people; which he perceived by the letter he sent him, and by his solicitous concern to build an house for the worship and honour of God, and by various other things which his ambassadors reported to him they had seen and heard in Solomon's court.

FURNISHES TIMBER TO BUILD THE TEMPLE. (1-Kings 5:7-12)
Blessed be the Lord--This language is no decisive evidence that Hiram was a worshipper of the true God, as he might use it only on the polytheistic principle of acknowledging Jehovah as the God of the Hebrews (see on 2-Chronicles 2:11).

Rejoiced - Being a faithful friend to David and his house, and tho' it is not probable he was a sincere proselyte, yet he had sufficient information concerning the nature and excellency of the God of Israel, and had honourable thoughts of him.
