Yea, I will rejoice over them to do them good,.... His covenant people, to whom he gives one heart and one way, and who have his fear implanted in them, and shall never depart from him, but persevere to the end: these he loves with a love of complacency and delight; he rejoices over them, not as considered in themselves, but as in Christ; he rejoices over them, as the bridegroom rejoices over the bride; and which does not merely lie in expression, but appears in fact; he does them good, and with the utmost joy and pleasure; he delights in showing mercy to them, beautifies them with salvation, and takes pleasure in their prosperity; he has taken up good thoughts and resolutions concerning them in his heart; has promised good things to them in his covenant; has provided good things for them in his Son, and bestows them on them in regeneration; and constantly supplies them with his grace, and will withhold no good thing from them, till he has brought them to glory; all which he does cheerfully and with the utmost delight The Targum is,"my Word shall rejoice over them;''the essential Word, Christ; he was rejoicing in them, and his delights were with them from eternity; he rejoices over them, as his lost sheep found at conversion; and they shall be his joy and crown of rejoicing to all eternity; and it was for the joy of having them with him that he endured so much for them in the redemption of them:and I will plant them in this land assuredly; or "in truth", or "in stability and firmness" ; for it does not seem so much to relate to the truth of the promise, and the assurance that may be had of the fulfilment of that, as to the reality and constancy of the blessing itself.

Grotius thinks these clauses are to be connected with the former part of the verse, that God will rejoice over them to do them good with all his heart and soul; but this the accents will not admit of; but the meaning is, that he will do this particular good for them, as well as all others, in the most cordial and respectable manner, even planting and establishing them in their own land.
The Targum is,"by my Word, and by my will.'
