Jeremiah 31:31-33

31"Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah,

32not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord.

33For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.
