The Jews answered him, “We have a law, and by that law he must die, because he made himself the Son of God.”
In context
5So Jesus came out, wearing the crown of thorns and the purple robe. Pilate said to them, “Here is the man!” 6When the chief priests and the guards saw him, they shouted, “Crucify! Crucify!” Pilate said to them, “Take him yourselves and crucify him. I find no case against him.” 7The Jews answered him, “We have a law, and by that law he must die, because he made himself the Son of God.” 8When Pilate heard this, he was more afraid than ever. 9He went back into the residence and asked Jesus, “Where are you from?” But Jesus gave him no answer.
