Matthew Poole and continuators on Deuteronomy 30:6

6 And * the LORD thy God will circumcise thine heart , and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.

Or, For the Lord will circum[illegible: 1+ letters]ise thine heart, i. e. will by his Word and Spirit change and purge thy heart from all thine Idolatry and Superstition and Wickedness, and encline thy heart to love him, as it here follows. See Deut. 10. 16. And so this is produced to shew why and how those great things should be accomplished, God would first convert and sanctifie them, the fruit whereof should be this, that they should return and obey Gods commandements, and v. 8. and then should prosper in all things, v. 9. The Hebrew Vau is oft rendred sor, and notes the reason of a thing, as 1 King. 1. 21. and 18. 3, 4 Psal. 1. 3. and 5. 12. Isa. 16. 2. and 64. 5. And this promise principally respects the times of the Gospel, and the Grace which was to be then imparted to all Gods Israel by Christ, by whom alone this circumcision is obtained, Col. 2. 11. And so having fully described to them the Law of God, the Rule of their obedience here▪ and in the foregoing chapters, and considering their great instability in the performance of their obedience to it, he now seasonably adds a glorious Gospel promise, and directs their faith to the Messias by whom alone they could expect or receive the establishment of their hearts in the ways of God against Apostacy.
