Psalms 78:51

And smote all the firstborn in Egypt,.... From the prince to the peasant; and not only the firstborn of men, but of beasts also,

Exodus 12:29,

the chief of their strength; or first of it, as the firstborn is called, Genesis 49:3,

in the tabernacles of Ham; in the several cities, towns, villages, and houses of the Egyptians, the descendants of cursed Ham; for Mizraim, from whom the Egyptians have their name, and from whence they sprung, was a son of Ham's, Genesis 10:6. Perhaps No Ammon may be particularly meant, Nahum 3:8, the same with Memphis, and which signifies the mansion or palace of Ammon, that is, Ham; and so Chemmis, another city in Egypt, signifies the same n; of which see Psalms 105:23 this was the tenth and last plague: according to Suidas o, the plagues of Egypt continued forty days.
