Exodus 14:30 - Joseph Benson’s Commentary on the Old and New Testaments

Israel saw the Egyptians dead upon the sea-shore Rather, Israel upon (or from) the sea-shore saw the Egyptians dead That is, saw their dead bodies floating upon the waters. It is likely, however, that the bodies of many of them were cast on shore, and became food to the beasts and birds of prey that frequent the wilderness, which may be the meaning of Psalms 74:14; and that the Israelites had the benefit of the spoil, especially of their arms, which they wanted. The Egyptians were very curious in preserving the bodies of their great men; but here the utmost contempt is poured upon the grandees of Egypt: see how they lie, heaps upon heaps, as dung upon the face of the earth!
