Malachi 4 in plain modern English. New Ground English Translation.

Look, the day is coming, and it burns like a kiln. Every arrogant person and everyone who does harm will be dry stalks, and the day that is coming will set them alight, says Yahweh who commands armies, and leave them no root and no branch.

But for you who fear my name, the sun of justice will rise with healing in its wings. You will come out and kick up your heels like calves let loose from the stall.

You will walk all over the ones who did harm. They will be ash under the soles of your feet on the day I act, says Yahweh who commands armies.

Keep in mind the teaching of Moses my servant, the rules and the rulings I gave him at Horeb for all Israel.

Look, I am sending you Elijah the prophet before the day of Yahweh comes, the great and terrifying day.

He will turn the hearts of parents back toward their children and the hearts of children back toward their parents, so that I do not come and put the land under the ban.
