15 Now it shall come to pass in that day that Tyre will be forgotten seventy years, according to the days of one king. At the end of seventy years it will happen to Tyre as in the song of the harlot: 16 "Take a harp, go about the city, You forgotten harlot; Make sweet melody, sing many songs, That you may be remembered." 17 And it shall be, at the end of seventy years, that the Lord will visit Tyre. She will return to her hire, and commit fornication with all the kingdoms of the world on the face of the earth. 18 Her gain and her pay will be set apart for the Lord; it will not be treasured nor laid up, for her gain will be for those who dwell before the Lord, to eat sufficiently, and for fine 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.
