But certain worthless fellows said, "How shall this man save us?" They despised him, and brought him no present. But he held his peace. Now Nahash, king of the Ammonites, was severely oppressing the Gadites and the Reubenites. He put out the right eye of all of them, and he would not allow anyone to rescue Israel. Not one was left of the children of Israel beyond the Jordan whose right eye Nahash, king of the Ammonites, did not put out, except for seven thousand men who had escaped from the Ammonites and went to Jabesh Gilead.

Behold, this day thy eyes have seen how the LORD hath delivered thee to-day into my hand in the cave; and some bade me kill thee: but my eye spared thee; and I said, I will not put forth my hand against my lord; for he is the LORD'S anointed.

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.

But Nahash the Ammonite said to them, "On this [condition] {I will make a treaty} with you, by gouging out the right eye of each of you, so that I can make it a disgrace for all Israel."

So Saul was keeping an eye on David from that day onward.

But keep an eye on it. If it should go up by the way of its own border to Beth Shemesh, then he has brought this great calamity on us. But if that is not the case, then we will know that it was not his hand that struck us; rather, it just happened to us by accident."
