If so, the host who invited both of you will come and say to you, 'Give this person your seat.' Then, humiliated, you will have to take the least important place. (NIV)
And he who invited both of you will come to you and say, Let this man have the place [you have taken]. Then, with humiliation and a guilty sense of impropriety, you will begin to take the lowest place. (AMP)
And he that bade thee and him come and say to thee, Give this man place; and thou begin with shame to take the lowest room. (KJV)
