“Then said they vnto him, Who art thou, that we may giue an answere to them that sent vs? What sayest thou of thy selfe?”
1611 King James Version (KJV)
Joh 1:22,23 Who art thou? When the priests and Levites insisted that John should declare who he was, he quoted Isaiah, and said he was The voice of one crying in the wilderness. See Isa 40:3. See PNT "Mt 3:3". His work was preparation for the Lord.
