Matthew Henry on 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.
