Jeremiah 31:31-33

31Behold, the days come, saith Jehovah, that I will make a new covenant with the house of Israel, and with the house of Judah: 32not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was a husband unto them, saith Jehovah. 33But this is the covenant that I will make with the house of Israel after those days, saith Jehovah: I will put my law in their inward parts, and in their heart will I write it; and I will be their God, and they shall be my people.
