2 Samuel 2:1, 3, 11

In the course of time, David inquired of the LORD. “Shall I go up to one of the towns of Judah?” he asked. The LORD said, “Go up.” David asked, “Where shall I go?” “To Hebron,” the LORD answered.

David also took the men who were with him, each with his family, and they settled in Hebron and its towns.

The length of time David was king in Hebron over Judah was seven years and six months.
