The one who invited both of you may come and say to you, 'Give your place to this man,' and then in humiliation, you will proceed to take the lowest place.
"But when you are invited, go and recline in the lowest place, so that when the one who invited you comes, he will say to you, 'Friend, move up higher.' You will then be honored in the presence of all the other guests.
For everyone who exalts himself will be humbled, and the one who humbles himself will be exalted."
He also said to the one who had invited Him, "When you give a lunch or a dinner, don't invite your friends, your brothers, your relatives, or your rich neighbors, because they might invite you back, and you would be repaid.
On the contrary, when you host a banquet, invite those who are poor, maimed, lame, or blind.
And you will be blessed, because they cannot repay you; for you will be repaid at the resurrection of the righteous."
When one of those who reclined at the table with Him heard these things, he said to Him, "The one who will eat bread in the kingdom of God is blessed!"
