This chapter gives the church and people of God reason to expect comfortable times and certain salvation, though they had many enemies. They are directed to look to Abraham and Sarah, signified by the rock and hole of the pit, and observe how he was called alone, blessed and increased; which should be improved as an argument to strengthen their faith, that God could and would bless and increase his church, though in a low estate, and bring it into a flourishing one, Isa 51:1.
They are assured of the publication of the Gospel, expressed by the law, doctrine, and judgment of the Lord; by which means the righteousness and salvation of Christ should be brought nigh to them, as the object of their trust and confidence, Isa 51:4, and also of the perpetuity of his righteousness and salvation, when the heavens, and the earth, and the inhabitants of it, should decay, even their revilers and persecutors, and therefore they need not fear their reproaches and revilings, Isa 51:6, upon which follows a prayer of faith, that the Lord would exert his power as in former times, when he destroyed the Egyptians, and dried up the Red sea for Israel to pass through, the ransomed of the Lord; from whence it might be concluded, that the redeemed of the Lord would be brought into a very comfortable condition again, Isa 51:9 wherefore they had no reason to be afraid of men, since the Lord, the Maker of heaven and earth, would deliver, comfort, and establish them, of which he assured them by his prophet, Isa 51:12, and though Jerusalem and her sons were, or would be, in a very distressed condition, through the sword and famine, which is described, Isa 51:17, yet they should be delivered out of it, and their persecutors should be brought into the same, Isa 51:21.
Ver. 1. Hearken unto me, ye that follow after righteousness,.... After having declared the doom of the wicked, and those that trust to their own righteousness, the Lord returns to them that fear him, whom he describes as such that "follow after righteousness"; not the righteousness of the law, it is the character of carnal Israel to follow after that; nor is that attainable in the way it is pursued by such; nor is there any justification by it; nor is following that consistent with seeking the Lord, in the next clause: but the righteousness of Christ is meant; not his essential righteousness as God; nor the righteousness of his office as Mediator; but that which consists of his active and passive obedience; of which he is the author and giver, and is in him as its subject: this is what is commonly called imputed righteousness, an evangelical one, the righteousness of faith, and is justifying: "following after" this supposes a want of one; a sense of that want; a view of this as out of themselves, and in another; a love and liking of it, and a vehement desire for it; and what determines to an eager pursuit of it are its perfection, suitableness, and use: now such persons are called to hearken to the Lord; to the Word of the Lord, as the Targum; to Christ, to his Gospel, and to his ordinances, particularly to what is after said:ye that seek the Lord: the Lord Christ, for life and salvation; for righteousness and strength; for more grace from him; a greater knowledge of him, and of doctrine from him, as the Targum; and more communion with him; that seek his honour and glory in the world, and to be for ever with him; who seek first the kingdom of God, and his righteousness; that seek him where he may be found, affectionately and sincerely, carefully, diligently, constantly, and for everything they want:look unto the rock whence ye are hewn; which is in the next verse interpreted of Abraham; so called, not so much for the strength of his faith, as for his old age; when he looked like a hard dry rock, from whom no issue could be expected; and yet from hence a large number of stones were hewn, or a race of men sprung:and to the hole of the pit whence ye are digged; that is, to Sarah, who was for a long time barren, whose womb was shut up, but afterwards opened; and from whom, as from a cistern, (to which a wife is sometimes compared, Pr 5:15) flowed the waters of Judah, Isa 48:1 or the Jewish nation.
