Mark 11:31-33

New Revised Standard Version, Anglicised

³¹ They argued with one another, ‘If we say, “From heaven”, he will say, “Why then did you not believe him?” ³² But shall we say, “Of human origin”?’—they were afraid of the crowd, for all regarded John as truly a prophet. ³³ So they answered Jesus, ‘We do not know.’ And Jesus said to them, ‘Neither will I tell you by what authority I am doing these things.’
