From the alternative Holy Communion Gospel for this week:

Jesus cried with a loud voice, ‘Lazarus, come out!’ The dead man came out, his hands and feet bound with strips of cloth, and his face wrapped in a cloth. Jesus said to them, ‘Unbind him, and let him go.’
(John’s Gospel, chapter 11, verses 43-44, NRSV)

I wonder why Jesus told them to “let him go”?
