"When you give a lunch or a dinner, do not invite only your friends or your relatives or your wealthy neighbors, so that they may invite you back. You will then have your reward. Rather, when you hold a banquet, invite the poor, the crippled, the lame, the blind; you will be blessed indeed because of their inability to repay you. For your goodness will be rewarded at the resurrection of the righteous."
Luke 14:12-14
