15 In that day Tyre will be forgotten for seventy years, like the days[1] of one king. At the end of seventy years, it will happen to Tyre as in the song of the prostitute: 16 "Take a harp; go about the city, O forgotten prostitute! Make sweet melody; sing many songs, that you may be remembered." 17 At the end of seventy years, the Lord will visit Tyre, and she will return to her wages and will prostitute herself with all the kingdoms of the world on the face of the earth. 18 Her merchandise and her wages will be holy to the Lord. It will not be stored or hoarded, but her merchandise will supply abundant food and fine clothing for those who dwell before the Lord.
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.
