John 1:23 In-Context

21 And they questioned him, `What then? Elijah art thou?' and he saith, `I am not.' -- `The prophet art thou?' and he answered, `No.'

22 They said then to him, `Who art thou, that we may give an answer to those sending us? what dost thou say concerning thyself?'

23 He said, `I [am] a voice of one crying in the wilderness: Make straight the way of the Lord, as said Isaiah the prophet.'

24 And those sent were of the Pharisees,

25 and they questioned him and said to him, `Why, then, dost thou baptize, if thou art not the Christ, nor Elijah, nor the prophet?'
