Luke 14: 12 - 14
12 He said also to the man who had invited him, "When you give a dinner or a banquet, do not invite your friends or your brothers or your kinsmen or rich neighbors, lest they also invite you in return, and you be repaid.
13 But when you give a feast, invite the poor, the maimed, the lame, the blind,
14 and you will be blessed, because they cannot repay you. You will be repaid at the resurrection of the just."
