How did Lazarus betray Jesus?

Lazarus did not betray Jesus. Lazarus was a friend of Jesus. He became ill and died. Jesus arrived three days later. His family had great faith, and they lamented that if Jesus had only arrived sooner, He could have healed Lazarus, and Lazarus would have lived. Jesus astonished everyone when he raised his friend from the dead and commanded his to rise up and walk out from his tomb.
