Dilean appears only in Joshua's boundary descriptions as one of the cities in Judah's inheritance. Located in the Shephelah region, it was part of the same district as Lachish and Eglon. The town's exact location remains uncertain to archaeologists, though it clearly belonged to Judah's western settlements in the fertile lowlands. The name itself may relate to roots suggesting 'hanging' or 'dangling,' though this etymology is speculative. Like many minor towns in Joshua's lists, Dilean represents the detailed fulfillment of God's land promises to the tribes.
