Malachi 4:5-6
Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD: And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.
The Lord promises us that he will send us Elijah before the great and dreadful day of the Lord, also known as judgement day. This is the same messenger that is talked about in Chapter 3 of Malachi. As we will see next week, John the Baptist is filling this role.
