Where are they? - This whole verse is an appeal by the prophet to the king of Egypt respecting the counselors and soothsayers of his kingdom. The sense is, 'a time of distress and danger is evidently coming upon Egypt. They pretend to be wise; and there is now occasion for all their wisdom, and opportunity to evince it. Let them show it. Let them declare what is coming upon the nation, and take proper measures to meet and remove it; and they will then demonstrate that it would be proper for Pharaoh to repose confidence in them.' But if they could not do this, then he should not suffer himself to be deluded, and his kingdom ruined, by their counsels.

"Let them come" - Here too a word seems to have been left out of the text. After חכמיך chochameycha, thy wise men, two MSS., one ancient, add יבאו yibu, let them come; which, if we consider the form and construction of the sentence, has very much the appearance of being genuine: otherwise the connective conjunction at the beginning of the next member is not only superfluous but embarrassing. See also the Version of the Septuagint, in which the same deficiency is manifest.

Let them tell thee now "And let them declare" - For ידעו yidu, let them know, perhaps we ought to read יודיעו yodiu, let them make known. - Secker. The Septuagint and Vulgate favor this reading, ειπατωισαν, let them declare.

Where are they? where are thy wise men?.... The magicians and soothsayers, the diviners and astrologers, who pretended, by their magic art and skill in judicial astrology, to foretell things to come: this is an address to the king of Egypt, who had such persons about him, and encouraged them, by consulting them on occasion, and rewarding them:

and let them tell thee now, and let them know what the Lord of hosts hath purposed upon Egypt; or, "against it"; let them tell, if they can, and make known unto thee the purposes of God's heart, the things he has resolved upon, even the calamities and punishments he will shortly inflict upon the Egyptians, of which he has given notice by his prophets.

Where are they? where are thy wise men? and let them tell thee now, and let them know what the LORD of hosts hath purposed upon Egypt.

12. let them know-that is, How is it that, with all their boast of knowing the future [Diodorus, 1.81], they do not know what Jehovah of hosts .

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.
