Matthew 17:3

Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD:

And there appeared unto them Elias with Moses: and they were talking with Jesus.

And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.

The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it.

And Elijah the Tishbite, who was of the inhabitants of Gilead, said unto Ahab, As the LORD God of Israel liveth, before whom I stand, there shall not be dew nor rain these years, but according to my word.

I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.

And it came to pass, as they departed from him, Peter said unto Jesus, Master, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elias: not knowing what he said.

And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.

And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord.

And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face,

For the law was given by Moses, but grace and truth came by Jesus Christ.
