Charles Ellicott Commentary 2 Chronicles 7:3

"And all the children of Israel looked on, when the fire came down, and the glory of Jehovah was upon the house; and they bowed themselves with their faces to the ground upon the pavement, and worshipped, and gave thanks unto Jehovah, [saying], For he is good; for his lovingkindness [endureth] for ever." — 2 Chronicles 7:3 (ASV)

Upon the pavement. — Riçpâh; rendered by the Septuagint τὸ λιθόστρωτον, which is the word used in John 19:13; Vulgate, “pavimentum stratum lapide.” (Esther 1:6, a tessellated pavement.)

And praised. —Gave thanks to Jehovah. The infinitive is here used for the finite form of the verb, as elsewhere.

For he is good; for his mercy endureth for ever. —See 1 Chronicles 16:34–41; 1 Chronicles 23:30; 2 Chronicles 5:13; 2 Chronicles 20:21. The Syriac and Arabic paraphrase, “and they said one to another: Give thanks to the Lord,” etc. There is hardly anything in the section, except this last phrase, which can be said to be characteristic of the style of the chronicler.
