1 Samuel 4:7

And the Philistines were afraid, for they said, God is come into the camp. Like all heathen, they had a superstitious fear of the supernatural, also of the deities of their enemies. Moreover, the Philistines feared the power of the God of the Israelites all the more, since the fame of His powerful deeds in former times had come to their ears. And they said, in consternation and fear, Woe unto us! For there hath not been such a thing heretofore. This expedient had never been adopted by Israel before this.
