The list of men described as leaders of Simeon's wealthy clans (1 Chronicles 4:34–38) leads into the description of Simeon's geographic expansion (4:38–43). The tribe expanded with thirteen family leaders during Hezekiah's time (late 700s BC) in the Gerar area. This might have been part of Hezekiah's military action against Philistine territories (2 Kings 18:8).
