Malachi 4:5-6

a Behold, I will send you b Elijah the prophet c before the great and awesome day of the  Lord comes. And he will d turn the hearts of fathers to their children and the hearts of children to their fathers, lest I come and e strike the land with a decree of utter destruction.”
The Hebrew term rendered  decree of utter destruction refers to things devoted (or set apart) to the Lord (or by the Lord) for destruction
