Observe, 1. How the people of God are here described, to whom the word of this consolation is sent and who are called upon to hearken to it, Isa 51:1. They are such as follow after righteousness, such as are very desirous and solicitous both to be justified and to be sanctified, are pressing hard after this, to have the favour of God restored to them and the image of God renewed on them. These are those that seek the Lord, for it is only in the say of righteousness that we can seek him with any hope of finding him. 2. How they are here directed to look back to their original, and the smallness of their beginning: "Look unto the rock whence you were hewn" (the idolatrous family in Ur of the Chaldees, out of which Abraham was taken, the generation of slaves which the heads and fathers of their tribes were in Egypt); "look unto the hole of the pit out of which you were digged, as clay, when God formed you into a people." Note, It is good for those that are privileged by a new birth to consider what they were by their first birth, how they were conceived in iniquity and shapen in sin. That which is born of the flesh is flesh. How hard was that rock out of which we were hewn, unapt to receive impressions, and how miserable the hole of that pit out of which we were digged! The consideration of this should fill us with low thoughts of ourselves and high thoughts of divine grace. Those that are now advanced would do well to remember how low they began (Isa 51:2): "Look unto Abraham your father, the father of all the faithful, of all that follow after the righteousness of faith as he did (Rom 4:11), and unto Sarah that bore you, and whose daughters you all are as long as you do well. Think how Abraham was called alone, and yet was blessed and multiplied; and let that encourage you to depend upon the promise of God even when a sentence of death seems to be upon all the means that lead to the performance of it. Particularly let it encourage the captives in Babylon, though they are reduced to a small number, and few of them left, to hope that yet they shall increase so as to replenish their own land again." When Jacob is very small, yet he is not so small as Abraham was, who yet became father of many nations. "Look unto Abraham, and see what he got by trusting in the promise of God, and take example by him to follow God with an implicit faith." 3. How they are here assured that their present seedness of tears should at length end in a harvest of joys, Isa 51:3. The church of God on earth, even the gospel Zion, has sometimes had her deserts and waste places, many parts of the church, through either corruption or persecution, made like a wilderness, unfruitful to God or uncomfortable to the inhabitants; but God will find out a time and way to comfort Zion, not only by speaking comfortably to her, but by acting graciously for her. God has comforts in store even for the waste places of his church, for those parts of it that seem not regarded or valued. (1.) He will make them fruitful, and so give them cause to rejoice; her wildernesses shall put on a new face, and look pleasant as Eden, and abound in all good fruits, as the garden of the Lord. Note, It is the greatest comfort of the church to be made serviceable to the glory of God, and to be as his garden in which he delights. (2.) He will make them cheerful, and so give them hearts to rejoice. With the fruits of righteousness, joy and gladness shall be found therein; for the more holiness men have, and the more good they do, the more gladness they have. And where there is gladness, to their satisfaction, it is fit that there should be thanksgiving, to God's honour; for whatever is the matter of our rejoicing ought to be the matter of our thanksgiving; and the returns of God's favour ought to be celebrated with the voice of melody, which will be the more melodious when God gives songs in the night, songs in the desert.

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, Pro 5:15) flowed the waters of Judah, Isa 48:1 or the Jewish nation. Jerom thinks Christ is meant by both, the Rock of ages, in whom is everlasting strength; to whom men are to look for salvation, righteousness, and strength; and out of whose pierced side flowed blood and water: and in this sense he is followed by Cocceius, who interprets the rock of Christ, the Rock of salvation; out of whose side flowed the church, as out of the hole of a pit or cistern.
