19. And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:
19. Et dabo illis cor unum, et spiritum novurn ponam in visceribus eorum, et tollam cor lapideum e carne ipsorum, et dabo ipsis cor carneum.
20. That they may walk in my statutes, and keep mine ordinances, and do them: and they shall be my people, and I will be their God.
20. Ut in statutis meis ambulent, et jndicia mea custodiant, et faciant ea: et erunt mihi in populum, et ego ero ipsis in Deum.
As God had already spoken concerning the piety of the Israelites, he shows that they could not forsake their sins until they were renewed, and so born again by his Spirit. Therefore he seemed in the last verse to praise the Israelites; but because men too eagerly claim as their own what has been given them from above, now God claims to himself glow of their virtues, of which he had formerly spoken. Their zeal in purging the land of all abominations was worthy of praise; hence the survivors of the people of Israel are deservedly celebrated, because they were impelled by the fervor of zeal to free the worship of God from all corruptions; but lest they should boast, that they had done it in their own strength, and from the impulse of their own hearts, God now modifies his former assertions, and shows that such pursuit of piety would exist among the Israelites, after he had regenerated them by his Spirit. And this plea alone may suffice to refute the Papists, as often as they seize upon such passages from the Scriptures, where God either exacts something from his people, or proclaims their virtues. David does this; hence he does it of his own free will: God requires this; hence it is in the will of men that they are equal to the performance of all things. Thus they trifle. But we see that the Prophet unites two things together, namely, the faithful elect of God strenuously attending to their duty, and intent on promoting his glory, even with ardor in the pursuit of his worship; and yet they were nothing by themselves. Hence it is added immediately afterwards -- I will give them one heart, and will put a new spirit in their breasts But we must defer the rest to the next lecture.
