Albert Barnes 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)

See the note on 1 Kings 6:2. In Jewish eyes, at the time the temple was built, it may have been "great"; that is to say, it may have exceeded the dimensions of any single building in Palestine before its construction.

Great is our God... — This may seem inappropriate when addressed to a pagan king. But it appears from 2 Chronicles 2:11–12 that Hiram acknowledged Yahweh as the supreme deity, probably identifying Him with his own god, Melkarth.
