Malachi 4 New Revised Standard Version Catholic Edition (NRSVCE)
The Great Day of the Lord
4 [a] See, the day is coming, burning like an oven, when all the arrogant and all evildoers will be stubble; the day that comes shall burn them up, says the Lord of hosts, so that it will leave them neither root nor branch. 2 But for you who revere my name the sun of righteousness shall rise, with healing in its wings. You shall go out leaping like calves from the stall. 3 And you shall tread down the wicked, for they will be ashes under the soles of your feet, on the day when I act, says the Lord of hosts.
4 Remember the teaching of my servant Moses, the statutes and ordinances that I commanded him at Horeb for all Israel.
5 Lo, I will send you the prophet Elijah before the great and terrible day of the Lord comes. 6 He will turn the hearts of parents to their children and the hearts of children to their parents, so that I will not come and strike the land with a curse.[b]
