John Wesley on Isaiah 23:4

Zidon - Zidon was a great city near Tyre, strongly united to her by commerce and league, and called by some the mother of Tyre, which they say, was built and first inhabited by a colony of the Sidonians. The sea - That part of the sea in which Tyre was, and from which ships and men were sent into all countries. The strength - Tyre might be called the strength of the sea, because it defendeth that part of the sea from piracies and injuries. I travel not - I, who was so fruitful, that I sent forth colonies into other countries (of which Carthage was one), am now barren and desolate.
