He didn’t say this because he cared about the poor but because he was a thief. He was in charge of the money-bag and would steal part of what was put in it.
Since Judas kept the money-bag, some thought that Jesus was telling him, ‘Buy what we need for the festival,’ or that he should give something to the poor.
So my people come to you in crowds, sit in front of you, and hear your words, but they don’t obey them. Their mouths go on passionately, but their hearts pursue dishonest profit.
