Charles Ellicott Commentary 2 Chronicles 1:9

"Now, O Jehovah God, let thy promise unto David my father be established; for thou hast made me king over a people like the dust of the earth in multitude." — 2 Chronicles 1:9 (ASV)

Now, O Lord God, let your promise to David my father be established. — A reminiscence of 1 Chronicles 17:23.

Over a people like the dust of the earth in multitude. — Over a people numerous as the dust of the earth. This last clause freely corresponds with 1 Kings 3:8. (Compare the common title of Assyrian monarchs, “king of multitudes,” sar kissâti.)
