John Wesley on 1 Samuel 4:8

Wo, &c. - They secretly confess the Lord to be greater than their gods, and yet presume to oppose him. Wilderness - They mention the wilderness, not as if all the plagues of the Egyptians came upon them in the wilderness, but because the last and sorest of all, which is therefore put for all, the destruction of Pharaoh and all his host, happened in the wilderness, namely, in the Red - sea, which having the wilderness on both sides of it, may well be said to be in the wilderness. Altho' it is not strange if these Heathens did mistake some circumstance in relation of the Israelitish affairs, especially some hundreds of years after they were done.
