1 Chronicles 21:16

Here a picture of awful grandeur takes the place of the bare statement of the earlier historian 2 Samuel 24:17. And here, as elsewhere, the author probably extracts from the ancient documents such circumstances as harmonize with his general plan. As the sanctity of the temple was among the points whereon he was most anxious to lay stress, he gives in full all the miraculous circumstances attending this first designation of what became the temple site (marginal reference “k”) as a place “holy to the Lord.”

David and the elders ... clothed in sackcloth, fell upon their faces - Facts additional to the narrative of Samuel; But facts natural in themselves, and in harmony with that narrative. Similarly, the narrative in 1 Chronicles 21:20 is additional to the account in Samuel; but its parts hang together; and there is no sufficient ground for suspecting it.
