3. What they shall bring with them and what advantage shall accrue to the church by their accession to it. Those that are brought into the church by the grace of God will be sure to bring all they are worth in with them, which with themselves they will devote to the honour and service of God and do good with in their places. (1.) The merchants shall write holiness to the Lord upon their merchandise and their hire, as ch. xxiii. 18. "The abundance of the sea, either the wealth that is fetched out of the sea (the fish, the pearls) or that which is imported by sea, shall all be converted to thee and to thy use." The wealth of the rich merchants shall be laid out in works of piety and charity. (2.) The mighty men of the nations shall employ their might in the service of the church: "The forces, or troops, of the Gentiles shall come unto thee, to guard thy coasts, strengthen thy interests, and, if occasion be, to fight thy battles." The forces of the Gentiles had often been against the church, but now they shall be for it; for as God, when he pleases, can, and, when we please him, will, make even our enemies to be at peace with us (Prov. xvi. 7), so, when Christ overcomes the strong man armed, he divides his spoils, and makes that to serve his interests which had been used against them, Luke xi. 22. (3.) The wealth imported by land-carriage, as well as that by sea, shall be made use of in the service of God and the church (v. 6): The camels and dromedaries that bring gold and incense (gold to make the golden altar of and incense and sweet perfumes to burn upon it), those of Midian and Sheba, shall bring the richest commodities of their country, not to trade with, but to honour God with, and not in small quantities, but camel-loads of them. This was in part fulfilled when the wise men of the east (perhaps some of the countries here mentioned), drawn by the brightness of the star, came to Christ, and presented to him treasures of gold, frankincense, and myrrh, Matt. ii. 11. (4.) Great numbers of sacrifices shall be brought to God's altar, acceptable sacrifices, and, though brought by Gentiles, they shall find acceptance, v. 7. Kedar was famous for flocks, and probably the fattest rams were those of Nebaioth; these shall come up with acceptance on God's altar. God must be served and honoured with what we have, according as he has blessed us, and with the best we have. This was fulfilled when by the decree of Darius the governors beyond the rivers (perhaps of some of these countries) were ordered to furnish the temple at Jerusalem with bullocks, rams, and lambs, for the burnt-offering of the God of heaven, Ezra vi. 9. It had a further accomplishment, and we trust will have, in the bringing in of the fulness of the Gentiles to the church, which is called the sacrificing or offering up of the Gentiles unto God, Rom. xv. 16. The flocks and rams are precious souls; for they are said to minister to the church, and to come up as living sacrifices, presenting themselves to God by a reasonable service on his altar, Rom. xii. 1.
