Commentary on Isaiah Volume 2 John Calvin (continued)
JOHN CALVIN
therefore, Isaiah accommodated to the capacity of the people, that they might know that the covenant into which God entered with the fathers was firm, sure, and eternal, and not changeable or temporary.
This is also what he means by the mercies of David, but by this phrase he declares that it was a covenant of free grace; for it was founded on nothing else than the absolute goodness of God. Whenever, therefore, the word "covenant" occurs in Scripture, we ought at the same time to call to remembrance the word "grace." By calling them "the faithful mercies of David," 325 he declares that he will be faithful in it, and at. the same time states indirectly that he is faithful and steadfast, and cannot be accused of falsehood, as if he had broken his covenant; that the Jews, on the other hand, are covenantbreakers and traitors, (for they have revolted from him,) but that he cannot repent of his covenant or his promise.
He calls them "the mercies of David," because this covenant, which has now been solemnly confirmed, was made in the land "of David." The Lord indeed entered into a covenant with Abraham, (Genesis 15:5; 17:7) afterwards confirmed it by Moses, (Exodus 2:24; 33:1) and finally ratified this very covenant in the hand of David, that it might be eternal. (2 Samuel 7:12) Whenever, therefore, the Jews thought of a Redeemer, that is, of their salvation, they ought to have remembered "David" as a mediator who represented Christ; for David must not here be regarded as a private individual, but as bearing this title and character. Yet some regard must be had to the time when this prophecy was uttered; for, since the rank of the kingdom had been obliterated, and the name of the royal family had become mean and contemptible during the captivity in Babylon, it might seem as if, through the ruin of that family, the truth of God had fallen into decay; and therefore he bids them contemplate by faith the throne of David, which had been cast down.
4. Behold, I have given him a witness to the peoples. The Prophet now explains more fully the reason why he mentioned "David." It was because into his hand had been committed the promise of a Redeemer that was to come, and this discourse might be expressed with a view to his public character, so far as he was the surety of the covenant; for he did not act for himself individually, but was appointed to be a sort of mediator between God and the people. Yet it is beyond all doubt that the Prophet leads them directly to Christ, to whom the transition from David was easy and natural; as if he had said, "That successor of David shall come forth, by whose hand perfect salvation and happiness hath been promised."
By calling him "a witness," he means that the covenant into which he entered shall be ratified and confirmed in Christ. There is a weighty meaning in the word "witness;" for he clearly shows that this covenant shall be proved in Christ, by whom the truth of God shall be made manifest. He will! testify that God is not false. But this testimony consists in doctrine; and if it were
