wherefore do ye not know my speech? because ye are not able to hear my word.

Who of you doth convict me of sin? and if I speak truth, wherefore do ye not believe me?

'Wherefore was not this ointment sold for three hundred denaries, and given to the poor?'

Peter saith to him, 'Sir, wherefore am I not able to follow thee now? my life for thee I will lay down;'
