Malachi 4:5
“Behold, I will send you Elijah the prophet before the great and awesome day of the LORD comes.
Matthew 11:7-15
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?What then did you go out to see? A man dressed in soft clothing? Behold, those who wear soft clothing are in kings’ houses.What then did you go out to see? A prophet? Yes, I tell you, and more than a prophet.This is he of whom it is written,
“‘Behold, I send my messenger before your face,
who will prepare your way before you.’
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.From the days of John the Baptist until now the kingdom of heaven has suffered violence,and the violent take it by force.For all the Prophets and the Law prophesied until John,and if you are willing to accept it, he is Elijah who is to come.He who has ears to hear, let him hear.
Ecclesiastes 1:9
What has been is what will be, and what has been done is what will be done, and there is nothing new under the sun.
