Orland Gibbons (1583-1625) wrote this absolutely beautiful anthem on John the Baptist, one of my favorite figures in the New Testament. From time-to-time, I search youtube for recordings of the song. This is not the one I have on my iTunes, but I think this vocalist is phenomenal.
Gospel of John 1:19-23
This is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou? And he confessed and denied not, and said plainly, I am not the Christ.
And they asked him, What art thou then? (Art thou Elias? repeated x1) And he said, I am not. (Art thou the prophet? repeated x1) And he answered, No.
Then said they unto him, What art thou? that we may give an answer unto them that sent us. What sayest thou of thyself? And he said, I am the voice of him that crieth in the wilderness, (Make straight the way of the Lord repeated x2)
