Isaiah 40:3-6   3. ¶The voice of him that crieth in the wilderness, Prepare ye the way of the LORD, make straight in the desert a highway for our God. 4. Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain: 5. And the glory of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD hath spoken it. 6. The voice said, Cry. And he said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field:

Mark 1:1-11   1. The beginning of the gospel of Jesus Christ, the Son of God; 2. As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee. 3. The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight. 4. John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins. 5. And there went out unto him all the land of Judaea, and they of Jerusalem, and were all baptized of him in the river of Jordan, confessing their sins. 6. And John was clothed with camel's hair, and with a girdle of a skin about his loins; and he did eat locusts and wild honey; 7. And preached, saying, There cometh one mightier than I after me, the latchet of whose shoes I am not worthy to stoop down and unloose. 8. I indeed have baptized you with water: but he shall baptize you with the Holy Ghost. 9. And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in Jordan. 10. And straightway coming up out of the water, he saw the heavens opened, and the Spirit like a dove descending upon him: 11. And there came a voice from heaven, saying, Thou art my beloved Son, in whom I am well pleased.

John 3:22-36   22. ¶After these things came Jesus and his disciples into the land of Judaea; and there he tarried with them, and baptized. 23. ¶And John also was baptizing in Aenon near to Salim, because there was much water there: and they came, and were baptized. 24. For John was not yet cast into prison. 25. ¶Then there arose a question between some of John's disciples and the Jews about purifying. 26. And they came unto John, and said unto him, Rabbi, he that was with thee beyond Jordan, to whom thou barest witness, behold, the same baptizeth, and all men come to him. 27. John answered and said, A man can receive nothing, except it be given him from heaven. 28. Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him. 29. He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled. 30. He must increase, but I must decrease. 31. He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: he that cometh from heaven is above all. 32. And what he hath seen and heard, that he testifieth; and no man receiveth his testimony. 33. He that hath received his testimony hath set to his seal that God is true. 34. For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him. 35. The Father loveth the Son, and hath given all things into his hand. 36. He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
