Tob was a district where Jephthah took refuge after being driven from home by his half-brother. He remained there with a band of men until the elders of Gilead recalled him.
The land of Tob is also associated with the men who joined the Ammonites against Israel.
It lay not far from Gilead, toward the eastern deserts. Later references connect it with Ishtob and with the Tubieni or people of Tob, but no certain modern identification is given.
