Tyndale Open Study Notes1 Chronicles 11

David first became king of Judah in Hebron and ruled there for seven and a half years (1 Chronicles 3:4; 2 Samuel 5:5). The Chronicler does not include the details of that time (see 2 Samuel 2–4) and instead focuses on David’s 33 and a half years ruling the entire nation. This began with his agreement with all the elders of Israel at Hebron (see 2 Samuel 5:1–5).

David conquered and rebuilt Jerusalem, making it the capital city of his rule over all of Israel.

This story about David's mighty warriors shows that Israel's best and bravest men supported him, along with all of Israel (compare 2 Samuel 23:8–39).

As the Lord promised, God chose David to be king, not David or the people (compare 1 Chronicles 11:3; 1 Samuel 16:11–14).

Zabad...Jaasiel: These warriors, not mentioned in 2 Samuel 23, came from places east of the Jordan River. David had strong support from all the tribes of Israel and from foreigners.
