Malachi.
Chapter 4.
“That time of judgment is coming. It will be like a hot furnace. All the proud people will be punished. All the evil people will burn like straw. At that time they will be like a bush burning in the fire, and there will not be a branch or root left.” This is what the LORD All-Powerful said. 
“But, for my followers, goodness will shine on you like the rising sun. And it will bring healing power like the sun’s rays. You will be free and happy, like calves freed from their stalls. 
Then you will walk on the evil people—they will be like ashes under your feet. I will make this happen at the time of judgment.” This is what the LORD All-Powerful said. 
“Remember and obey the law of my servant Moses. I gave those laws and rules to him at Mount Horeb. They are for all the people of Israel. 
“Look, I will send Elijah the prophet to you. He will come before that great and terrible time of judgment from the LORD. 
Elijah will help the parents become close to their children, and he will help the children become close to their parents. This must happen, or I will come and completely destroy your country.”
