Malachi 4:5-6

Wycliffe Bible

⁵ Lo! I shall send to you Elijah, the prophet, before that the great day and horrible of the Lord come. (Lo! I shall send you the prophet Elijah, before that the great and terrible day of the Lord shall come.)

⁶ And he shall turn again the heart of fathers to sons, and the heart of sons to the fathers of them, lest peradventure I come, and smite the earth with (a) curse. Amen. (And he shall turn the hearts of the fathers toward their sons, and the hearts of the sons toward their fathers, lest perhaps I come, and strike the land with a curse, and destroy it. Amen.)
