They go from strength to strength,.... Whose strength is in the Lord, and in whose heart are his ways, and who pass through the valley of Baca, and find a well of supply, and pools of blessings there; they renew their spiritual strength; they grow stronger and stronger every step they take; the way of the Lord is strength unto them: or "from army to army", or "from company to company" (d), as Kimchi, alluding to the companies in which they went up to the feasts; see Luk 2:44 when those who were more zealous, or more able to undergo journeys, would outgo the rest, and first overtake one company, and then another, and get to Zion first: or from victory to victory: first overcoming one enemy, and then another, as sin, Satan, and the world, being more than conquerors through him that has loved them: or "from doctrine to doctrine" (e); being led first into one truth, and then into another, as they were able to bear them; and so following on to know the Lord, and increasing in the knowledge of him: or "from class to class" (f); from the lower to an higher form in the school of Christ; so Jarchi interprets it, from school to school; and the Targum, from the sanctuary to the school; compare with this Rom 1:17. everyone of them in Zion appeareth before God; three times in the year, but not empty, Exo 34:20 so the saints appear before God in his church below, presenting their persons, souls and bodies, prayers and praises, as holy and spiritual sacrifices unto him; than which nothing is more desirable to them. This is the wished for happiness, and the issue of their travel, toil, and labour; see Psa 42:2, and they shall appear before him, and in his presence, in the, church above; when Christ shall appear, they shall appear with him in glory, and be like him, and see him as he is; even everyone of them, not one shall be wanting; because he is great in power, not one of them shall fail; and he will present them to his Father, saying, lo, I and the children thou hast given me: some render the words, "the God of gods will appear", or "be seen in Zion" (g); there Jehovah manifests himself, and grants his gracious presence; this is the mount of the Lord, in which he is and shall be seen, Gen 22:14.
