David was anointed king over Judah at Hebron. Hebron was a city in the southern part of the land of Canaan, which later became the territory of the tribe of Judah. After the death of Saul, the first king of Israel, David was anointed as king over Judah by the people of that tribe. It was later after Ish-bosheth, the son of Saul was killed that David was anointed as king over all Israel at Hebron.
