The LORD of hosts hath purposed it, to stain the pride of all glory, and to bring into contempt all the honourable of the earth.

Wesley's Notes

23:9 The Lord - This is the Lord's own doing. To stain - God's design is by this example to abase the pride of all the potentates of the earth.

King James Translators' Notes

to stain: Heb. to pollute

Jamieson-Fausset-Brown Bible Commentary

9. Whoever be the instruments in overthrowing haughty sinners, God, who has all hosts at His command, is the First Cause (Isa 10:5-7).

stain-rather, "to profane"; as in Ex 31:14, the Sabbath, and other objects of religious reverence; so here, "the pride of all glory" may refer to the Tyrian temple of Hercules, the oldest in the world, according to Arrian (Isa 2:16); the prophet of the true God would naturally single out for notice the idol of Tyre [G. V. Smith]. It may, however, be a general proposition; the destruction of Tyre will exhibit to all how God mars the luster of whatever is haughty (Isa 2:11).

Matthew Henry's Concise Commentary

23:1-14 Tyre was the mart of the nations. She was noted for mirth and diversions; and this made her loth to consider the warnings God gave by his servants. Her merchants were princes, and lived like princes. Tyre being destroyed and laid waste, the merchants should abandon her. Flee to shift for thine own safety; but those that are uneasy in one place, will be so in another; for when God's judgments pursue sinners, they will overtake them. Whence shall all this trouble come? It is a destruction from the Almighty. God designed to convince men of the vanity and uncertainty of all earthly glory. Let the ruin of Tyre warn all places and persons to take heed of pride; for he who exalts himself shall be abased. God will do it, who has all power in his hand; but the Chaldeans shall be the instruments.
