Jeremiah 43:12

And I will kindle a fire in the houses of the gods of Egypt, to show the helplessness of the idols in the country whose security the Jews were seeking; and he shall burn them and carry them away captives, the very gods of Egypt being in his power; and he shall array himself with the land of Egypt as a shepherd putteth on his garment, and he shall go forth from thence in peace. The point of comparison is the freedom and the ease of the act; for just as easily and quickly as a shepherd takes up his mantle, practically his only garment, and wraps it about him, so easily will Nebuchadnezzar take hold upon Egypt and, with the whole country in his power, leave without hindrance, with no one opposing him.
