Tribe of Judah: Make David King

Some time later, David inquired of the LORD, “Should I go up to one of the towns of Judah?” “Go up,” the LORD answered. Then David asked, “Where should I go?” “To Hebron,” replied the LORD. …

David was thirty years old when he became king, and he reigned forty years.

In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned thirty-three years over all Israel and Judah.
