4 and I will give over the Egyptians into the hand of a hard master; and a fierce king will rule over them, says the Lord, the Lord of hosts. 5 And the waters of the Nile will be dried up, and the river will be parched and dry; 6 and its canals will become foul, and the branches of Egypt's Nile will diminish and dry up, reeds and rushes will rot away.
Matthew Henry's Commentary on Isaiah 19:4-6
Commentary on Isaiah 19:1-17
(Read Isaiah 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.
