Malachi 4:5

¹⁷He will go before him in the spirit and power of Elijah, ‘to turn the hearts of the fathers to the children,’and the disobedient to the wisdom of the just; to prepare a people prepared for the Lord.”

¹⁰His disciples asked him, saying, “Then why do the scribes say that Elijah must come first?”

¹¹Jesus answered them, “Elijah indeed comes first, and will restore all things; ¹²but I tell you that Elijah has come already, and they didn’t recognize him, but did to him whatever they wanted to. Even so the Son of Man will also suffer by them.” ¹³Then the disciples understood that he spoke to them of John the Baptizer.

¹¹They asked him, saying, “Why do the scribes say that Elijah must come first?”

¹²He said to them, “Elijah indeed comes first, and restores all things. How is it written about the Son of Man, that he should suffer many things and be despised? ¹³But I tell you that Elijah has come, and they have also done to him whatever they wanted to, even as it is written about him.”

^13[+] For all the prophets and the law prophesied until John. ¹⁴If you are willing to receive it, this is Elijah, who is to come.

¹“Behold, I send my messenger, and he will prepare the way before me! The Lord, whom you seek, will suddenly come to his temple. Behold, the messenger of the covenant, whom you desire, is coming!” says the LORD of Armies.

³The voice of one who calls out, “Prepare the way of the LORD in the wilderness! Make a level highway in the desert for our God.

²¹They asked him, “What then? Are you Elijah?” He said, “I am not.” “Are you the prophet?” He answered, “No.”

³¹The sun will be turned into darkness, and the moon into blood, before the great and terrible day of the LORD comes.

¹“For behold, the day comes, 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 the LORD of Armies, “so that it will leave them neither root nor branch.

²⁶But what did you go out to see? A prophet? Yes, I tell you, and much more than a prophet. ²⁷This is he of whom it is written, ‘Behold, I send my messenger before your face, who will prepare your way before you.’

²⁸“For I tell you, among those who are born of women there is not a greater prophet than John the Baptizer; yet he who is least in God’s Kingdom is greater than he.”
