When he noticed how the guests chose the places of honor, he told them a parable. “When you are invited by someone to a wedding banquet, do not sit down at the place of honor, in case someone more distinguished than you has been invited by your host, and the host who invited both of you may come and say to you, ‘Give this person your place,’ and then in disgrace you would start to take the lowest place.
“But when you are invited, go and sit down at the lowest place, so that when your host comes, he may say to you, ‘Friend, move up higher’; then you will be honored in the presence of all who sit at the table with you.
“For all who exalt themselves will be humbled, and those who humble themselves will be exalted.”

[Ἔλεγεν δὲ πρὸς τοὺς κεκλημένους παραβολήν, ἐπέχων πῶς τὰς πρωτοκλισίας ἐξελέγοντο, λέγων πρὸς αὐτούς, Ὅταν κληθῇς ὑπό τινος εἰς γάμους, μὴ κατακλιθῇς εἰς τὴν πρωτοκλισίαν, μήποτε ἐντιμότερός σου ᾖ κεκλημένος ὑπ᾽ αὐτοῦ, καὶ ἐλθὼν ὁ σὲ καὶ αὐτὸν καλέσας ἐρεῖ σοι, Δὸς τούτῳ τόπον, καὶ τότε ἄρξῃ μετὰ αἰσχύνης τὸν ἔσχατον τόπον κατέχειν.
ἀλλ᾽ ὅταν κληθῇς, πορευθεὶς ἀνάπεσε εἰς τὸν ἔσχατον τόπον, ἵνα ὅταν ἔλθῃ ὁ κεκληκώς σε ἐρεῖ σοι, Φίλε, προσανάβηθι ἀνώτερον· τότε ἔσται σοι δόξα ἐνώπιον πάντων τῶν συνανακειμένων σοι.
ὅτι πᾶς ὁ ὑψῶν ἑαυτὸν ταπεινωθήσεται, καὶ ὁ ταπεινῶν ἑαυτὸν ὑψωθήσεται.]

And he put forth a parable to those which were bidden, when he marked how they chose out the chief rooms; saying unto them, 8 When thou art bidden of any man to a wedding, sit not down in the highest room; lest a more honourable man than thou be bidden of him; 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.
But when thou art bidden, go and sit down in the lowest room; that when he that bade thee cometh, he may say unto thee, Friend, go up higher: then shalt thou have worship in the presence of them that sit at meat with thee.
For whosoever exalteth himself shall be abased; and he that humbleth himself shall be exalted.
[KJV (1611)]

He then told the guests a parable, because he had noticed how they picked the places of honour. He said this, "When someone invites you to a wedding feast, do not take your seat in the place of honour. A more distinguished person than you may have been invited, and the person who invited you both may come and say, 'Give up your place to this man.' And then, to your embarrassment, you would have to go and take the lowest place.
"No; when you are a guest, make your way to the lowest place and sit there, so that, when your host comes, he may say, 'My friend, move up higher.' In that way, everyone with you at the table will see you honoured.
"For everyone who exalts himself will be humbled, and the man who humbles himself will be exalted."
[JB (1966)]

Jesus noticed how some of the guests were choosing the best places, so he told this parable to all of them: “When someone invites you to a wedding feast, do not sit down in the best place. It could happen that someone more important than you has been invited, and your host, who invited both of you, would have to come and say to you, ‘Let him have this place.’ Then you would be embarrassed and have to sit in the lowest place.
"Instead, when you are invited, go and sit in the lowest place, so that your host will come to you and say, ‘Come on up, my friend, to a better place.’ This will bring you honor in the presence of all the other guests.
"For those who make themselves great will be humbled, and those who humble themselves will be made great.”
[GNT (1992 ed.)]

When Jesus noticed how the guests sought out the best seats at the table, he told them a parable. “When someone invites you to a wedding celebration, don’t take your seat in the place of honor. Someone more highly regarded than you could have been invited by your host. The host who invited both of you will come and say to you, ‘Give your seat to this other person.’ Embarrassed, you will take your seat in the least important place.
"Instead, when you receive an invitation, go and sit in the least important place. When your host approaches you, he will say, ‘Friend, move up here to a better seat.’ Then you will be honored in the presence of all your fellow guests.
"All who lift themselves up will be brought low, and those who make themselves low will be lifted up."
