'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.

So the elders of Jabesh said to him, "Leave us alone for seven days so that we may send messengers in all the territory of Israel, and if there [is] no deliverer for us, then we will come out to you."

For as surely as the Lord, the deliverer of Israel, lives, even if it turns out to be my own son Jonathan, he will certainly die!" But no one from the army said anything.
