Charles H. Spurgeon on Psalms 72:10

The kings of Tarshish and of the isles shall bring presents. Trade shall be made subservient to the purposes of mediatorial rule; merchant princes, both far and near, shall joyfully contribute of their wealth to his throne. Seafaring places are good centres from which to spread the gospel; and seafaring men often make earnest heralds of the cross. Tarshish of old was so far away, that to the eastern mind it was lost in its remoteness, and seemed to be upon the verge of the universe; even so far as imagination itself can travel, shall the Son of David rule; across the blue sea shall his sceptre be stretched; the white cliffs of Britain already own him, the gems of the Southern Sea glitter for him, even Iceland's heart is warm with his love. Madagascar leaps to receive him; and if there be isles of the equatorial seas whose spices have as yet not been presented to him, even there shall he receive a revenue of glory. He has made many an islet to become a Holy Isle, and hence, a true Formosa. The kings of Sheba and Seba shall offer gifts. Agriculture and pasturage shall contribute their share. Foreign princes from inland regions, as yet unexplored, shall own the all embracing monarchy of the King of kings; they shall be prompt to pay their reverential tribute. Religious offerings shall they bring, for their King is their God. Then shall Arabia Felix be happy indeed, and the Fortunate Isles be more than fortunate. Observe, that true religion leads to generous giving; we are not taxed in Christ's dominions, but we are delighted to offer freely to him. It will be a great day when kings will do this: the poor widow has long ago been before them, it is time that they followed; their subjects would be sure to imitate the royal example. This free will offering is all Christ and his church desire; they want no forced levies and distraints, let all men give of their own free will, kings as well as commoners; alas! the rule has been for kings to give their subjects' property to the church, and a wretched church has received this robbery for a burnt offering; it shall not be thus when Jesus more openly assumes the throne.
