Jer. 31:31-33

Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel , and with the house of Judah :

Not 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 an husband unto them, saith the LORD:

But this [shall be] the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
