Late that afternoon, the followers came to Jesus and said, “No people live in this place. And it is already late. Send the people away so they can go to the towns and buy food for themselves.”
Judas was the one that kept the money box \{for the group\}. So some of the followers thought that Jesus meant for Judas to go and buy some things they needed for the feast. Or they thought that Jesus wanted Judas to go give something to the poor people.
