I refer to St Luke 16:19
The Parable of he Rich Man and the Poor Man
The poor man was VERY poor... a homeless beggar
The rich man walked by him a lot of the time and gave him nothing.
the rich man went to Hell (see Mt 25:31...) and the poor one went to Abraham's bosom
The rich man in Hell was thirsty and begged the poor man to give him a drop of water but was told (by Abraham?) that there is a great divide btwn those 2 places and no one can go from one side to the other
The rich man pleaded for his brothers still on Earth, said that if the poor man returned from the dead, they would listen to him
But Abraham said that "They have the prophets. If they will not listen to the prophets, they will not listen even were one to return from the dead"
