A (5) Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of Yahweh:

B (6) And he shall turn the heart of the fathers

C (6) to the children,

C1 (6) and the heart of the children

B1 (6) to their fathers,

A1 (6) lest I come and smite the earth with a curse.
