John Gill Commentary 2 Chronicles 1

And Solomon the son of David was strengthened in his kingdom ,
&c.] Well settled and established on the throne of his father, after the death of some persons, from whom he might expect trouble, see (1 Kings 2:46)

and the Lord God was with him ;
directing and instructing him, prospering and succeeding him: the Targum is,

the Word of the Lord was his help:

and magnified him exceedingly; see (1 Chronicles 29:25) .

Then Solomon spoke unto all Israel
To their representatives about going to Gibeon to sacrifice, as the next words show: so Jarchi and Kimchi observe:

to the captains of thousands, and of hundreds, to the judges, and to
every governor in all Israel, the chief of the fathers ;
whom he had convened on this occasion; though some think this is the same congregation gathered by his father, by whom he was anointed and made king, and that he spoke of this to them before they broke up, (1 Chronicles 28:1) (29:22) which seems not so probable, since it was after the death of his father, after he had been king some time, and even after his marriage with Pharaoh's daughter, that what follows was done, see (1 Kings 3:1–4) .

So Solomon, and all the congregation with him, went to the high
place that was at Gibeon
They agreed to his motion, and went with him thither, see (1 Kings 3:4)

for there was the tabernacle of the congregation of God, which Moses
the servant of the Lord had made in the wilderness :
by the Lord's direction; where was also the altar of the Lord, and so most proper to offer sacrifice on, which was what Solomon went thither to do; see (1 Chronicles 21:29) .

But the ark of God had David brought up from Kirjathjearim ,
&c.] See (2 Samuel 6:2 2 Samuel 6:17) .

Moreover, the brazen altar that Bezaleel the son of Uri, the
son of Hur, had made
According to the pattern given by Moses, at the direction of God, (Exodus 38:1),

he put before the tabernacle of the congregation ;
either David, or rather Solomon; though it seems best to read the words as in the Septuagint and VulgateLatin versions, "and there it was before the tabernacle"; for it was always there:

and Solomon and the congregation sought unto it ;
to sacrifice unto it; or rather sought "unto him", the Lord, before whose tabernacle the altar was, soGussetins ^F1 .
