1 Chronicles 18

4-8. And David took from him a thousand In 2 Samuel 8:4 David is said to have taken seven hundred horsemen, whereas here it is said that he took seven thousand. This great discrepancy in the text of the two narratives seems to have originated with a transcriber in confounding the two Hebrew letters which indicate the numbers, and in neglecting to mark or obscure the points over one of them. We have no means of ascertaining whether seven hundred or seven thousand be the more correct. Probably the former should be adopted [DAVIDSON'S HERMENUTICS].
but reserved of them an hundred chariots--probably to grace a triumphal procession on his return to Jerusalem, and after using them in that way, destroy them like the rest.

8. from Tibhath and from Chun--These places are called Betah and Berothai ( 2 Samuel 8:8 ). Perhaps the one might be the Jewish, the other the Syrian, name of these towns. Neither their situation nor the connection between them is known. The Arabic version makes them to be Emesa (now Hems) and Baal-bek, both of which agree very well with the relative position of Zobah.

9-13. Tou--or Toi--whose dominions border on those of Hadadezer.

17. the Cherethites and the Pelethites--who formed the royal bodyguard. The Cherethites were, most probably, those brave men who all along accompanied David while among the Philistines, and from that people derived their name ( 1 Samuel 30:14 , Ezekiel 25:16 , Zephaniah 2:5 ) as well as their skill in archery--while the Pelethites were those who joined him at Ziklag, took their name from Pelet, the chief man in the company ( 1 Chronicles 12:3 ), and, being Benjamites, were expert in the use of the sling.
