2 Samuel 2:1, 3, 11

After this David inquired of the LORD, “Shall I go up into any of the cities of Judah?” And the LORD said to him, “Go up.” David said, “To which shall I go up?” And he said, “To Hebron.”

And David brought up his men who were with him, everyone with his household, and they lived in the towns of Hebron.

And the time that David was king in Hebron over the house of Judah was seven years and six months.
