These mighty Gods; they secretly confess the Lord to be higher and greater than their gods, and yet against their knowledge presume to oppose him. 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, to wit, 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, Exodus 13:18,20 Exodus 15:3,11 15:22, &c., may well be said to be in the wilderness. Although it is not strange if these heathens did mistake and misreport some circumstance in a relation of the Israelitish affairs, especially some hundreds of years after they were done, such mistakes being frequent in divers heathen authors treating of those matters, as Justin, and Tacitus, and others.
