2 Samuel 5:3

Then Joshua and all Israel with him went up from Eglon to Hebron, and they fought against it.

Then the men of Judah came and there anointed David king over the house of Judah. And they told David, saying, “It was the men of Jabesh-gilead who buried Saul.”

“And Zadok the priest and Nathan the prophet shall anoint him there as king over Israel and blow the trumpet and say, ‘Long live King Solomon!’

Then Jehoiada cut a covenant between Yahweh and the king and the people, that they would be the people of Yahweh, also between the king and the people.

Then all Israel gathered to David at Hebron and said, “Behold, we are your bone and your flesh.

So all the elders of Israel came to the king at Hebron, and David cut a covenant with them in Hebron before Yahweh; then they anointed David king over Israel, according to the word of Yahweh through Samuel.

All these, being men of war who could draw up in battle lines, came to Hebron with their whole heart to make David king over all Israel; and all the rest also of Israel were of one heart to make David king.
