Malachi 4:2-6

2“But for you who fear My name, the sun of righteousness will rise with healing in its wings,1 and you will go out and leap like calves from the stall. 3Then you will trample the wicked, for they will be ashes under the soles of your feet on the day I am preparing,” says the LORD of Hosts.

4“Remember the law of My servant Moses, the statutes and ordinances I commanded him for all Israel at Horeb.2

5Behold, I will send you Elijah the prophet before the coming of the great and awesome3 Day of the LORD. 6And he will turn the hearts of the fathers to their children, and the hearts of the children to their fathers.4 Otherwise, I will come and strike the land with a curse.”
