Malachi 4

“For indeed, the day is coming, burning like a furnace, when all the proud and all who work wickedness will be stubble. The day that comes will burn them up,” says YHWH Almighty, “so that it will leave them neither root nor branch. But for y’all who fear my name, the sun of righteousness will arise with healing in its wings. Y’all will go out and run around like calves released from the stall. Y’all will trample on the wicked, and they will be ashes under the soles of y’all’s feet on the day which I am preparing,” says YHWH Almighty.

Y’all must remember the law of Moses my servant, even statutes and ordinances, which I gave to him in Horeb for all Israel.

Indeed, I will send y’all Elijah the prophet before the great and terrible day of YHWH comes. He will turn the hearts of the fathers to the children and the hearts of the children to their fathers, so that I will not come and strike the earth with a curse.”
