301 Now when all these things have come on you, the blessing and the curse which I have put before you, if the thought of them comes back to your minds, when you are living among the nations where the Lord your God has sent you, 2 And your hearts are turned again to the Lord your God, and you give ear to his word which I give you today, you and your children, with all your heart and with all your soul: 3 Then the Lord will have pity on you, changing your fate, and taking you back again from among all the nations where you have been forced to go. 4 Even if those who have been forced out are living in the farthest part of heaven, the Lord your God will go in search of you, and take you back; 5 Placing you again in the land of your fathers as your heritage; and he will do you good, increasing you till you are more in number than your fathers were. 6 And the Lord your God will give to you and to your seed a circumcision of the heart, so that, loving him with all your heart and all your soul, you may have life. 7 And the Lord your God will put all these curses on those who are against you, and on your haters who put a cruel yoke on you. 8 And you will again give ear to the voice of the Lord, and do all his orders which I have given you today.

Commentary on Deuteronomy 30:1-10
(Read Deuteronomy 30:1-10)
In this chapter is a plain intimation of the mercy God has in store for Israel in the latter days. This passage refers to the prophetic warnings of the last two chapters, which have been mainly fulfilled in the destruction of Jerusalem by the Romans, and in their dispersion to the present day; and there can be no doubt that the prophetic promise contained in these verses yet remain to come to pass. The Jewish nation shall in some future period, perhaps not very distant, be converted to the faith of Christ; and, many think, again settled in the land of Canaan. The language here used is in a great measure absolute promises; not merely a conditional engagement, but declaring an event assuredly to take place. For the Lord himself here engages to "circumcise their hearts;" and when regenerating grace has removed corrupt nature, and Divine love has supplanted the love of sin, they certainly will reflect, repent, return to God, and obey him; and he will rejoice in doing them good. The change that will be wrought upon them will not be only outward, or consisting in mere opinions; it will reach to their souls. It will produce in them an utter hatred of all sin, and a fervent love to God, as their reconciled God in Christ Jesus; they will love him with all their hearts, and with all their soul. They are very far from this state of mind at present, but so were the murderers of the Lord Jesus, on the day of Pentecost; who yet in one hour were converted unto God. So shall it be in the day of God's power; a nation shall be born in a day; the Lord will hasten it in his time. As a conditional promise this passage belongs to all persons and all people, not to Israel only; it assures us that the greatest sinners, if they repent and are converted, shall have their sins pardoned, and be restored to God's favour.
