Three of the thirty leaders went down to David at the rocky cliff at the cave of Adullam, while a Philistine force was camped in the Valley of Rephaim.

He received honor from ¹  the thirty warriors, though he was not one of the three elite warriors. David put him in charge of his bodyguard.

This is the list of David’s warriors: ¹  Jashobeam, a Hacmonite, was head of the officers. ²  He killed three hundred men with his spear in a single battle. ³ 

But a spirit ¹  empowered ²  Amasai, the leader of the thirty warriors, and he said: ³  “We are yours, O David! We support ⁴  you, O son of Jesse! May you greatly prosper! ⁵  May those who help you prosper! ⁶  Indeed ⁷  your God helps you!” So David accepted them and made them leaders of raiding bands.
