John 1:23 YLT

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?'
