But this shall be the covenant that I will make with the house of Israel; After those days, says the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
All Commentaries on Jeremiah 31:33 Go To Jeremiah 31
Augustine of Hippo
AD 430
God is the reward, in him the end, in him the perfection of happiness, in him the sum of the blessed and eternal life. For after saying, “I will be their God, and they shall be my people,” he at once adds, “And they shall no more teach everyone his neighbor, and everyone his brother, saying, Know the Lord; for they shall all know me, from the least to the greatest of them.”
