Zechariah 9:3
And Tyrus did build herself a strong hold, and heaped up silver as the dust, and fine gold as the mire of the streets.
And Tyrus did build herself a strong hold,.... Tyre was built upon a rock, and was a strong fortress itself, from whence it had its name; and, besides its natural defence, it had a wall one hundred and fifty feet high, and its breadth was answerable to its height {e}; but yet, as it could not defend itself against Alexander the great, who took it; so neither against the Gospel of Christ, which found its way into it, and was mighty to pull down strong holds in a spiritual sense:
and heaped up silver as the dust, and fine gold as the mire of the streets; the riches of these cities, especially Tyre, are often made mention of; they were famous for their wealth, being places of great trade and merchandise; see Isaiah 23:2 all which were to be holiness to the Lord, and for the sufficient feeding and durable clothing of them that dwell before him, Isaiah 23:18 his ministers.
