John 19 is a part of the Bible that talks about the crucifixion of Jesus Christ. That means that it tells the story of how Jesus was put on a cross to die. It's like a really sad story where the people who didn't like Jesus wanted him to suffer and die on the cross.
In the story, Jesus has some friends who feel really sad and scared for him. They watch as soldiers hurt Jesus and make fun of him. But Jesus stays really calm and strong, even though he's in a lot of pain.
A man named Pilate is in charge of deciding what to do with Jesus. Pilate thinks that Jesus didn't do anything wrong, but some other people want him dead. So Pilate agrees to let Jesus be punished on the cross.
Jesus dies on the cross, but his friends still remember him and tell other people about him. They believe that even though he died, he was really special and important. And that's why people still talk about Jesus today, even though this story is a really old one.
