Matthew 3:1-12 ESV
In those days John the Baptist came preaching in the wilderness of Judea, 2 “Repent, for the kingdom of heaven is at hand.” 3 For this is he who was spoken of by the prophet Isaiah when he said,
“The voice of one crying in the wilderness:
‘Prepare the way of the Lord;
make his paths straight.’”
4 Now John wore a garment of camel's hair and a leather belt around his waist, and his food was locusts and wild honey. 5 Then Jerusalem and all Judea and all the region about the Jordan were going out to him, 6 and they were baptized by him in the river Jordan, confessing their sins.
7 But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come? 8 Bear fruit in keeping with repentance. 9 And do not presume to say to yourselves, ‘We have Abraham as our father,’ for I tell you, God is able from these stones to raise up children for Abraham. 10 Even now the axe is laid to the root of the trees. Every tree therefore that does not bear good fruit is cut down and thrown into the fire.
11 “I baptize you with water for repentance, but he who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire. 12 His winnowing fork is in his hand, and he will clear his threshing floor and gather his wheat into the barn, but the chaff he will burn with unquenchable fire.”
Malachi 3:1 NASB
“Behold, I am sending My messenger, and he will clear a way before Me. And the Lord, whom you are seeking, will suddenly come to His temple; and the messenger of the covenant, in whom you delight, behold, He is coming,” says the Lord of armies.
Malachi 4:5 NASB
5 “Behold, I am going to send you Elijah the prophet before the coming of the great and terrible day of the Lord.
Luke 1:17 NASB
17 And it is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of fathers back to their children, and the disobedient to the attitude of the righteous, to make ready a people prepared for the Lord.”
Matthew 17:12-13 ESV
12 But I tell you that Elijah has already come, and they did not recognize him, but did to him whatever they pleased. So also the Son of Man will certainly suffer at their hands.” 13 Then the disciples understood that he was speaking to them of John the Baptist.
John 1:19-21 ESV
19 And this is the testimony of John, when the Jews sent priests and Levites from Jerusalem to ask him, “Who are you?” 20 He confessed, and did not deny, but confessed, “I am not the Christ.” 21 And they asked him, “What then? Are you Elijah?” He said, “I am not.”

14 and if you are willing to accept it, he is Elijah who is to come.
2 Kings 1:7-8 ESV
7 He said to them, “What kind of man was he who came to meet you and told you these things?” 8 They answered him, “He wore a garment of hair, with a belt of leather about his waist.” And he said, “It is Elijah the Tishbite.”

18 He said, “I have not brought disaster to Israel, but you and your father’s house have, because you have abandoned the commandments of the Lord and you have followed the Baals.

Now in the fifteenth year of the reign of Tiberius Caesar, when Pontius Pilate was governor of Judea, and Herod was tetrarch of Galilee and his brother Philip was tetrarch of the region of Ituraea and Trachonitis, and Lysanias was tetrarch of Abilene, 2 in the high priesthood of Annas and Caiaphas, the word of God came to John, the son of Zechariah, in the wilderness.
Matthew 14:4 ESV
4 because John had been saying to him, “It is not lawful for you to have her.”
1 Kings 18:1, 21 NASB
Now it happened after many days that the word of the Lord came to Elijah in the third year, saying, “Go, present yourself to Ahab, and I will provide rain on the face of the earth.”
21 Then Elijah approached all the people and said, “How long are you going to struggle with the two choices? If the Lord is God, follow Him; but if Baal, follow him.”
Matthew 11:7-11 ESV
7 As they went away, Jesus began to speak to the crowds concerning John: “What did you go out into the wilderness to see? A reed shaken by the wind? 8 What then did you go out to see? A man dressed in soft clothing? Behold, those who wear soft clothing are in kings' houses.9 What then did you go out to see? A prophet? Yes, I tell you, and more than a prophet. 10 This is he of whom it is written,
“‘Behold, I send my messenger before your face,
who will prepare your way before you.’
11 Truly, I say to you, among those born of women there has arisen no one greater than John the Baptist. Yet the one who is least in the kingdom of heaven is greater than he.
John 3:3 NASB
3 Jesus responded and said to him, “Truly, truly, I say to you, unless someone is born again he cannot see the kingdom of God.”
