1 Samuel 14:15-20

15And there was a trembling in the camp, in the field, and among all the people; the garrison, and the spoilers, they also trembled; and the earth quaked: so there was an exceeding great trembling.

16And the watchmen of Saul in Gibeah of Benjamin looked; and, behold, the multitude melted away, and they went hither and thither. 17Then said Saul unto the people that were with him, Number now, and see who is gone from us. And when they had numbered, behold, Jonathan and his armorbearer were not there. 18And Saul said unto Ahijah, Bring hither the ark of God. For the ark of God was there at that time with the children of Israel. 19And it came to pass, while Saul talked unto the priest, that the tumult that was in the camp of the Philistines went on and increased: and Saul said unto the priest, Withdraw thy hand. 20And Saul and all the people that were with him were gathered together, and came to the battle: and, behold, every man’s sword was against his fellow, and there was a very great discomfiture.
