Luke 14.

8 When someone invites you to a wedding feast, do not take the place of honour, for a person more distinguished than you may have been invited.
9 If so, the host who invited both of you will come and say to you, 'Give this man your seat.' Then, humiliated, you will have to take the least important place.
10 But when you are invited, take the lowest place, so that when your host comes, he will say to you, 'Friend, move up to a better place.' Then you will be honoured in the presence of all your fellow guests.

Often are the things mentioned in the bible very clever. They are not related directly to salvation but helps to lead a simple but happy and easy live. This example makes clear that a humble person will receive the honour he ought to receive. If you want to receive more than you are entitled to than you might get into an embarrassing situation.
