Verse 8

Simeon, Benjamin, and Enoch — Reuben’s son — went out on the west side of the tower, and 50 were with them. Of (the people of) Edom and the Horites they killed 400 strong warriors, and 600 ran away. Esau’s four sons ran away with them. They left their slain father just as he had fallen on the hill that is in Aduram.
