Mark 11:26-33

26 and, if ye do not forgive, neither will your Father who is in the heavens forgive your trespasses.'
27 And they come again to Jerusalem, and in the temple, as he is walking, there come unto him the chief priests, and the scribes, and the elders,
28 and they say to him, `By what authority dost thou these things? and who gave thee this authority that these things thou mayest do?'
29 And Jesus answering said to them, `I will question you -- I also -- one word; and answer me, and I will tell you by what authority I do these things;
30 the baptism of John -- from heaven was it? or from men? answer me.'
31 And they were reasoning with themselves, saying, `If we may say, From heaven, he will say, Wherefore, then, did ye not believe him?
32 But if we may say, From men,' -- they were fearing the people, for all were holding John that he was indeed a prophet;
33 and answering they say to Jesus, `We have not known;' and Jesus answering saith to them, `Neither do I tell you by what authority I do these things.'
