Jeremiah 31:33-34

31:33 “But this is 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 I will write it in their heart. I will be their God, and they shall be my people.

31:34 They will no longer each teach his neighbour, and every man teach his brother, saying, ‘Know the LORD;’ for they will all know me, from their least to their greatest,” says the LORD, “for I will forgive their iniquity, and I will remember their sin no more.”
