2 Samuel 5:3

1 Then all the tribes of Israel came to David in Hebron and said, Truly, we are your bone and your flesh.

2 In the past when Saul was king over us, it was you who went at the head of Israel when they went out or came in: and the Lord said to you, You are to be the keeper of my people Israel and their ruler.

3 So all the responsible men of Israel came to the king at Hebron; and King David made an agreement with them in Hebron before the Lord: and they put the holy oil on David and made him king over Israel.

4 David was thirty years old when he became king, and he was king for forty years,

5 Ruling over Judah in Hebron for seven years and six months, and in Jerusalem, over all Israel and Judah, for thirty-three years.

6 And the king and his men went to Jerusalem against the Jebusites, the people of the land: and they said to David, You will not come in here, but the blind and the feeble-footed will keep you out; for they said, David will not be able to come in here.
