Whence art thou? (pothen ei su). Pilate knew that Jesus was from Galilee (Luk 23:6.). He is really alarmed. See a like question by the Jews in Joh 8:25.
Gave him no answer (apokrisin ouk edōken autōi). See same idiom in Joh 1:22. Apokrisis (old word from apokrinomai) occurs also in Luk 2:47; Luk 20:26. The silence of Jesus, like that before Caiaphas (Mar 14:61; Mat 26:63) and Herod (Luk 23:9), irritates the dignity of Pilate in spite of his fears.
