1 Chronicles Chapter 18

Almost a repeat of 2 Sam 8.  Very little difference, not really any add'l info.

In the 2 Sam version, we are told that David took a lot of bronze from some of the cities of Hadadezer.   Here we are told that Solomon later uses this very bronze to construct the bronze sea and the pillars and the vessels of bronze for the first Temple.  There was a LOT of bronze.

2023 - This verse:

16 and Zadok the son of Ahitub and Ahimelech the son of Abiathar were priests; and Shavsha was secretary; [1Ch 18:16 ESV].  So this makes sense now.  The Ark was in a tent in Jerusalem, but everything else from the Tabernacle remained at Gideon.  So a priest was needed at each place.  Zadok was the "high priest" in Gideon, and apparently Ahimelech was in Jerusalem.  That's how I read it.  The  part about Zadok is certain because of 1Chr 16:39.  In that same chapter, though, it is Asaph that is left to sing before the ark in Jerusalem.  1Chr 16:5 says Asaph was chief of those appointed by David as ministers before the Ark.  Moving back still further, we find this confirming verses in 1Chr 15:  11 Then David summoned the priests Zadok and Abiathar, and the Levites Uriel, Asaiah, Joel, Shemaiah, Eliel, and Amminadab, 12 and said to them, "You are the heads of the fathers' houses of the Levites. Consecrate yourselves, you and your brothers, so that you may bring up the ark of the LORD, the God of Israel, to the place that I have prepared for it. [1Ch 15:11-12 ESV].  So while Asaph was a big deal, his duties were confined to that one area.  Abiathar was high priest in Jerusalem.  As always, it all fits just fine, without contradiction.
