John Gill Commentary 2 Chronicles 2:5

"And the house which I build is great; for great is our God above all gods." — 2 Chronicles 2:5 (ASV)

And the house which I build is great
Not so very large, though that, with all apartments and courts belonging to it, he intended to build, was so; but because magnificent in its structure and decorations:

for great is our God above all gods ;
and therefore ought to have a temple to exceed all others, as the temple at Jerusalem did.
