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.

17. Judah … terror unto Egypt—not by itself: but at this time Hezekiah was the active subordinate ally of Assyria in its invasion of Egypt under Sargon. Similarly to the alliance of Judah with Assyria here is 2Ki 23:29, where Josiah takes the field against Pharaoh-nechoh of Egypt, probably as ally of Assyria against Egypt [G. V. Smith]. Vitringa explains it that Egypt in its calamities would remember that prophets of Judah had foretold them, and so Judah would be "a terror unto Egypt."

thereof—of Judah.

it—Egypt.
