John 1:19-21

Young's Literal Translation

¹⁹ And this is the testimony of John, when the Jews sent out of Jerusalem priests and Levites, that they might question him, `Who art thou?'

²⁰ and he confessed and did not deny, and confessed -- `I am not the Christ.'

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