2 Samuel 2:1, 3, 11

After this, David asked the LORD, “Should I move back to one of the towns of Judah?” “Yes,” the LORD replied. Then David asked, “Which town should I go to?” “To Hebron,” the LORD answered.

and his men and their families all moved to Judah, and they settled in the villages near Hebron.

David made Hebron his capital, and he ruled as king of Judah for seven and a half years.
