3. What good effect it shall have upon them. (1.) It shall make them vigorous in themselves: "You shall go forth, as those that are healed go abroad and return to their business." The souls shall go forth out of their bodies at death, and the bodies out of their graves at the resurrection, as prisoners out of their dungeons, and both to see the light and be set at liberty. "You shall go forth as plants out of the earth, when in the spring the sun returns." Some make it to mean the going forth of the Christians from Jerusalem, and the escape they thereby made from its destruction. And thus the souls on whom the Sun of righteousness arises go forth out of the world, go forth out of Babylon, as those that are made free indeed. "You shall likewise grow up; being restored to health and liberty, you shall increase in knowledge, and grace, and spiritual strength." The souls on which the Sun of righteousness arises are growing up towards the perfect man; those that by the grace of God are made wise and good are by the same grace made wiser and better; and their path, like that of the rising sun, shines more and more to the perfect day, Prov. iv. 18. Their growth is compared to that of the calves of the stall, which is a quick, strong, and useful growth. "You shall grow up, not as the flower of the field, which is slender, and weak, and of little use, and withers soon after it has grown up, but as the calves of the stall," that, as one of the rabbin expounds it, grow great in flesh and fatness, with which both God's altars and men's tables are replenished; so the growth of the saints, on whom the Sun of righteousness arises, honours both God and man. Some read it, instead of You shall grow up, You shall move yourselves, or leap for joy, shall be as frolicsome as calves of the stall, when they are let loose in the open field; it denotes the joy of the saints, who rejoice in Christ Jesus; they shall even leap for joy; they are always caused to triumph.
