Charles Spurgeon Commentary Zechariah 9:1-4

"The burden of the word of Jehovah upon the land of Hadrach, and Damascus [shall be] its resting-place (for the eye of man and of all the tribes of Israel is toward Jehovah); and Hamath, also, which bordereth thereon; Tyre and Sidon, because they are very wise. And Tyre did build herself a stronghold, and heaped up silver as the dust, and fine gold as the mire of the streets. Behold, the Lord will dispossess her, and he will smite her power in the sea; and she shall be devoured with fire." — Zechariah 9:1-4 (ASV)

The burden of the word of the LORD in the land of Hadrach, and Damascus shall be the rest thereof: when the eyes of man, as of all the tribes of Israel, shall be toward the LORD. And Hamath also shall border thereby, Tyrus, and Zidon, though it be very wise. And Tyrus did build herself a stronghold, and heaped up silver as the dust, and fine gold as the mire of the streets. Behold, the Lord will cast her out, and he will smite her power in the sea; and she shall be devoured with fire.

Alexander the Great besieged Tyre, and utterly overthrew it. The citizens thought that their "strong hold" was impregnable, but they had at last to surrender to the mighty monarch whose attacks they had so long resisted. All the mercenaries whom they could procure with their heaped-up silver and gold could not avert the doom which the Lord had foretold, and which, through the instrumentality of Alexander, he accomplished: The Lord will cast her out, and he will smite her power in the sea.
