The “raving insolence of their tongue” may mean the boasts that were made of the friendship of King Shebaka of Egypt, who made Israel his tool. In the land of Egypt they would thus become objects of derision. (Comp. Isaiah’s warning to his countrymen, Isaiah 30:1-8.)

They are like a deceitful bow - Which, "howsoever the archer directs it, will not carry the arrow right home to the mark," but to other objects clean contrary to his will. : "God had, as it were, bent Israel, as His own bow, against the tyranny of the devil and the deceit of idolatry. For Israel alone in the whole world cast aside the worship of idols, and was attached to the true and natural Lord of all things. But they turned themselves to the contrary. For, being bound to this, they fought against God for the glory of idols. They became then as a warped bow, shooting their arrows contrariwise." In like way doth every sinner act, using against God, in the service of Satan, God's gifts of nature or of outward means, talents, or wealth, or strength, or beauty, or power of speech. God gave all for His own glory; and man turns all aside to do honor and service to Satan.

Their princes shall fall by the sword for the rage of their tongue - The word, rendered "rage," is everywhere else used of the wrath of God; here, of the "wrath" and "foaming" of man against God. Jeremiah relates how, the nearer their destruction came upon Judah, the more madly the politicians and false prophets cantradicted what God revealed. Their tongue was a "sharp sword." They sharpened their tongue like a sword; and the sword pierced their own bosom. The phrensy of their speech not only drew down God's anger, but was the instrument of their destruction. They misled the people; taught them to trust in Egypt, not in God; persuaded them to believe themselves, and to disbelieve God; to believe, that the enemy should depart from them and not carry them away captive. They worked up the people to their will, and so they secured their own destruction. The princes of Judah were especially judged and put to death by Nebuchadnezzar Jeremiah 52:10. The like probably took place in Israel. In any case, those chief in power are chief objects of destruction. Still more did these words come true before the final destruction of Jerusalem by the Romans. They were maddened by their own curse, "the rage of their tongue" against their Redeemer, "His blood be on us and on our children." Frenzy became their characteristic. It was the amazement of the Romans, and their own destruction.

This shall be their derision in the land of Egypt - This, i. e., all this, their boasting of Egypt, their failure, their destruction, shall become their "derision." In Egypt had they trusted; to Egypt had they gone for succor; in Egypt should they be derided. Such is the way of man. The world derides those who trusted in it, sued it, courted it, served it, preferred it to their God. Such are the wages, which it gives. So Isaiah prophesied of Judah, "the strength of Pharaoh shall be your shame, and the trust in the shadow of Egypt your confusion. They were all ashamed of a people that could not profit them, nor be an help nor profit, but a shame and also a reproach" Isaiah 30:3, Isaiah 30:5.

deceitful bow—(Ps 78:57). A bow which, from its faulty construction, shoots wide of the mark. So Israel pretends to seek God, but turns aside to idols.

for the rage of their tongue—their boast of safety from Egyptian aid, and their "lies" (Ho 7:13), whereby they pretended to serve God, while worshipping idols; also their perverse defense for their idolatries and blasphemies against God and His prophets (Ps 73:9; 120:2, 3).

their derision in … Egypt—Their "fall" shall be the subject of "derision" to Egypt, to whom they had applied for help (Ho 9:3, 6; 2Ki 17:4).

they are like a deceitful bow; which misses the mark it is directed to; which being designed to send its arrow one way, causes it to go the reverse; or its arrow returns upon the archer, or drops at his feet; so these people deviated from the law of God, acted contrary to their profession and promises, and relapsed into their former idolatries and impieties, and sunk into earth and earthly things; see Psalm 78:57;

their princes shall fall by the sword: either of their conspirators, as Zachariah, Shallum, Pekahiah, and Pekah; or by the sword of the Assyrians, as Hoshea, and the princes with him, by Shalmaneser;

for the rage of their tongue; their blasphemy against God, his being and providences; his worship, and the place of it; his priests and people that served him, and particularly the prophets he sent unto them to reprove them;

this shall be their derision in the land of Egypt; whither they sent, and called for help; but now, when their princes are slain, and they carried captive into a foreign land, even those friends and allies of theirs shall laugh and mock at them. The Targum is,

"these were their works while they were in the land of Egypt;''

or rather the words may be rendered, "this is their derision, as of old in the land of Egypt" (x); that is, the calves they now worshipped, and to which they ascribed all their good things, were made in imitation of the gods of Egypt, their Apis and Serapis, which were in the form of an ox, and which their fathers derided there; and these were justly to be derided now, and they to be derided for their worship of them, and ascribing all their good things to them; and which would be done when their destruction came upon them.
