'Deliverer' in the Bible

Meanwhile, Nahash, king of the Ammonites, had been severely oppressing the descendants of Gad and descendants of Reuben, gouging out their right eyes and not allowing Israel to have a deliverer. No one was left among the Israelis across the Jordan whose right eye Nahash, king of the Ammonites, had not gouged out. However, 7,000 men had escaped from the Ammonites and entered Jabesh-gilead.
