Charles H. Spurgeon on Psalms 107:3

And gathered them out of the lands, from the east, and from the west, from the north, and from the south. Gathering follows upon redeeming. The captives of old were restored to their own land from every quarter of the earth, and even from beyond the sea; for the word translated south is really the sea. No matter what divides, the Lord will gather his own into one body, and first on earth by "one Lord, one faith, and one baptism", and then in heaven by one common bliss they shall be known to be the one people of the One God. What a glorious Shepherd must, he be who thus collects the blood bought flock from the remotest regions, guides them through countless perils, and at last makes them to lie down in the green pastures of Paradise. Some have wandered one way and some another they have all left Immanuel's land and strayed as far as they could, and great are the grace and power by which they are all collected into one flock by the Lord Jesus. With one heart and voice let the redeemed praise the Lord who gathers them into one.
