John 1:29-37

The next day he saw Jesus coming to him and said, “Look! The Lamb of God who takes away the sin of the world! [Ex 12:3; Is 53:7] This is He on behalf of whom I said, ‘After me comes a Man who has a higher rank than I and has priority over me, for He existed before me.’ I did not recognize Him [as the Messiah]; but I came baptizing in water so that He would be [publicly] revealed to Israel.” John gave [further] evidence [testifying officially for the record, with validity and relevance], saying, “I have seen the Spirit descending as a dove out of heaven, and He remained upon Him. [Matt 3:13-17; Mark 1:9-11; Luke 3:22, 23] I did not recognize Him [as the Messiah], but He who sent me to baptize in water said to me, ‘He upon whom you see the Spirit descend and remain, this One is He who baptizes with the Holy Spirit.’ I myself have [actually] seen [that happen], and my testimony is that this is the Son of God!” Again the next day John was standing with two of his disciples, and he looked at Jesus as He walked along, and said, “Look! The Lamb of God!” The two disciples heard him say this, and they followed Jesus.
