Jesus first examined by Annas, the ex-High Priest

Joh 18:12-14,19-23
12 Then the band and the chief captain and the police took Jesus and put cords round him.
13 They took him first to Annas, because Annas was the father-in-law of Caiaphas who was the high priest that year.
14 It was Caiaphas who had said to the Jews that it was in their interest for one man to be put to death for the people.
19 Then the high priest put questions to Jesus about his disciples and his teaching.
20 Jesus made answer, I said things openly to the world at all times; I have given my teaching in the Synagogues and in the Temple to which all the Jews come; and I have said nothing secretly.
21 Why are you questioning me? put questions to my hearers about what I have said to them: they have knowledge of what I said.
22 When he said this, one of the police by his side gave him a blow with his open hand, saying, Do you give such an answer to the high priest?
23 Jesus said in answer, If I have said anything evil, give witness to the evil: but if I said what is true, why do you give me blows?
