15 It will come to pass in that day that Tyre will be forgotten seventy years, according to the days of one king. After the end of seventy years it will be to Tyre like in the song of the prostitute. 16 Take a harp; go about the city, you prostitute that has been forgotten. Make sweet melody. Sing many songs, that you may be remembered. 17 It will happen after the end of seventy years that Yahweh will visit Tyre, and she shall return to her wages, and will play the prostitute with all the kingdoms of the world on the surface of the earth. 18 Her merchandise and her wages will be holiness to Yahweh. It will not be treasured nor laid up; for her merchandise will be for those who dwell before Yahweh, to eat sufficiently, and for durable clothing.
Matthew Henry's Commentary on Isaiah 23:15-18
Commentary on Isaiah 23:15-18
(Read Isaiah 23:15-18)
The desolations of Tyre were not to be for ever. The Lord will visit Tyre in mercy. But when set at liberty, she will use her old arts of temptation. The love of worldly wealth is spiritual idolatry; and covetousness is spiritual idolatry. This directs those that have wealth, to use it in the service of God. When we abide with God in our worldly callings, when we do all in our power to further the gospel, then our merchandise and hire are holiness to the Lord, if we look to his glory. Christians should carry on business as God's servants, and use riches as his stewards.
