19:1-17 God shall come into Egypt with his judgments. He will raise up the causes of their destruction from among themselves. When ungodly men escape danger, they are apt to think themselves secure; but evil pursues sinners, and will speedily overtake them, except they repent. The Egyptians will be given over into the hand of one who shall rule them with rigour, as was shortly after fulfilled. The Egyptians were renowned for wisdom and science; yet the Lord would give them up to their own perverse schemes, and to quarrel, till their land would be brought by their contests to become an object of contempt and pity. He renders sinners afraid of those whom they have despised and oppressed; and the Lord of hosts will make the workers of iniquity a terror to themselves, and to each other; and every object around a terror to them.

11. Zoan—The Greeks called it Tanis, a city of Lower Egypt, east of the Tanitic arms of the Nile, now San; it was one the Egyptian towns nearest to Palestine (Nu 13:22), the scene of Moses' miracles (Ps 78:12, 43). It, or else Memphis, was the capital under Sethos.

I am … son of the wise … kings—Ye have no advice to suggest to Pharaoh in the crisis, notwithstanding that ye boast of descent from wise and royal ancestors. The priests were the usual "counsellors" of the Egyptian king. He was generally chosen from the priestly caste, or, if from the warrior caste, he was admitted into the sacred order, and was called a priest. The priests are, therefore, meant by the expression, "son of the wise, and of ancient kings"; this was their favorite boast (Herodotus, 2.141; compare Am 7:14; Ac 23:6; Php 3:5). "Pharaoh" was the common name of all the kings: Sethos, probably, is here meant.
