Jeremiah 31:31-34

“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. And each man will no longer teach his neighbor and his brother, saying, ‘Know the LORD,’ for they will all know Me [through personal experience], from the least of them to the greatest,” says the LORD. “For I will forgive their wickedness, and I will no longer remember their sin.” [Heb 8:8-12; 10:16, 17]
