'Discovered' in the Bible

The Philistines heard the sound of the war cry and asked, “What’s this loud shout in the Hebrews’ camp?” When the Philistines discovered that the ark of the Lord had entered the camp,

And both of them discovered themselves unto the garrison of the Philistines: and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves.

There was intense fighting against the Philistines during Saul's entire reign, and whenever Saul discovered a strong or valiant warrior, he would enlist him for service.

When Saul heard that David was discovered, and the men that were with him, (now Saul abode in Gibeah under a tree in Ramah, having his spear in his hand, and all his servants were standing about him;)

Saul camped beside the road at the hill of Hachilah opposite Jeshimon. David was living in the wilderness and discovered Saul had come there after him.

The next day, when the Philistines came to strip loot from the corpses, they discovered Saul and his three sons lying dead on Mount Gilboa.
