Jeremiah 31:31-33

“Behold, the days are coming,” says the LORD, “when I will make a new covenant with the house of Israel (the Northern Kingdom) and with the house of Judah (the Southern Kingdom), [Luke 22:20; 1 Cor 11:25] not like the covenant which I made with their fathers in the day when I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them,” says the LORD. “But this is the covenant which I will make with the house of Israel after those days,” says 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 will be My people.
