According to the author of 1 Chronicles, David collected a lot of brass from the cities he won, and later, his son Solomon used this brass to make important items for God’s temple, like a big basin and tall pillars. This shows how God helped David and Solomon to gather materials to build a special place for worship.
1 Chronicles 18:8: Likewise from Tibhath, and from Chun, cities of Hadarezer, brought David very much brass, wherewith Solomon made the brasen sea, and the pillars, and the vessels of brass. [Tibhath...: called in the book of Samuel Betah, and Berothai]
Describes the taking of brass from Betah and Berothai, whereas 1 Chronicles 18:8 mentions Tibhath and Chun, differing in names of locations.
2 Samuel 8:8: And from Betah, and from Berothai, cities of Hadadezer, king David took exceeding much brass.
