Matthew 21:25-27

WNT(i) 25 John's Baptism, whence was it? --had it a heavenly or a human origin?" So they debated the matter among themselves. "If we say 'a heavenly origin,'" they argued, "he will say, 'Why then did you not believe him?' 26 and if we say 'a human origin' we have the people to fear, for they all hold John to have been a Prophet." 27 So they answered Jesus, "We do not know." "Nor do I tell you," He replied, "by what authority I do these things."
