And he went on to say to them all, “Watch out and guard yourselves from every kind of greed; because your true life is not made up of the things you own, no matter how rich you may be.”
Then Jesus told them this parable: “There was once a rich man who had land which bore good crops. He began to think to himself, ‘I don’t have a place to keep all my crops. What can I do? This is what I will do,’ he told himself; ‘I will tear down my barns and build bigger ones, where I will store the grain and all my other goods. Then I will say to myself, Lucky man! You have all the good things you need for many years. Take life easy, eat, drink, and enjoy yourself!’ But God said to him, ‘You fool! This very night you will have to give up your life; then who will get all these things you have kept for yourself?’”
And Jesus concluded, “This is how it is with those who pile up riches for themselves but are not rich in God’s sight.”

εἶπεν δὲ πρὸς αὐτούς, Ὁρᾶτε καὶ φυλάσσεσθε ἀπὸ πάσης πλεονεξίας, ὅτι οὐκ ἐν τῷ περισσεύειν τινὶ ἡ ζωὴ αὐτοῦ ἐστιν ἐκ τῶν ὑπαρχόντων αὐτῷ.
Εἶπεν δὲ παραβολὴν πρὸς αὐτοὺς λέγων, Ἀνθρώπου τινὸς πλουσίου εὐφόρησεν ἡ χώρα. καὶ διελογίζετο ἐν ἑαυτῷ λέγων, Τί ποιήσω, ὅτι οὐκ ἔχω ποῦ συνάξω τοὺς καρπούς μου; καὶ εἶπεν, Τοῦτο ποιήσω, καθελῶ μου τὰς ἀποθήκας καὶ μείζονας οἰκοδομήσω καὶ συνάξω ἐκεῖ πάντα τὸν σῖτον καὶ τὰ ἀγαθά μου καὶ ἐρῶ τῇ ψυχῇ μου, Ψυχή, ἔχεις πολλὰ ἀγαθὰ κείμενα εἰς ἔτη πολλά· ἀναπαύου, φάγε, πίε, εὐφραίνου.
εἶπεν δὲ αὐτῷ ὁ θεός, Ἄφρων, ταύτῃ τῇ νυκτὶ τὴν ψυχήν σου ἀπαιτοῦσιν ἀπὸ σοῦ· ἃ δὲ ἡτοίμασας, τίνι ἔσται; οὕτως ὁ θησαυρίζων ἑαυτῷ καὶ μὴ εἰς θεὸν πλουτῶν.

And he said unto them, Take heed, and beware of covetousness: for a man’s life consisteth not in the abundance of the things which he possesseth.
And he spake a parable unto them, saying, The ground of a certain rich man brought forth plentifully: and he thought within himself, saying, What shall I do, because I have no room where to bestow my fruits? And he said, This will I do: I will pull down my barns, and build greater; and there will I bestow all my fruits and my goods. And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry.
But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided? So is he that layeth up treasure for himself, and is not rich toward God.
[KJV (1611)]

Then he said to them, 'Watch, and be on your guard against avarice of any kind, for a man's life is not made secure by what he owns, even when he has more than he needs'.
Then he told them a parable: 'There was once a rich man who, having had a good harvest from his land, thought to himself, "What am I to do? I have not enough room to store my crops." Then he said, "This is what I will do: I will pull down my barns and build bigger ones, and store all my grain and my goods in them, and I will say to my soul: My soul, you have plenty of good things laid by for many years to come; take things easy, eat, drink, have a good time". 'But God said to him, "Fool! This very night the demand will be made for your soul; and this hoard of yours, whose will it be then?". So it is when a man stores up treasure for himself in place of making himself rich in the sight of God.'
[JB (1966)]

Then he said to them, 'Watch, and be on your guard against avarice of any kind, for life does not consist in possessions, even when someone has more than he needs.'
Then he told them a parable, 'There was once a rich man who, having had a good harvest from his land, thought to himself, "What am I to do? I have not enough room to store my crops." Then he said, "This is what I will do: I will pull down my barns and build bigger ones, and store all my grain and my goods in them, and I will say to my soul: My soul, you have plenty of good things laid by for many years to come; take things easy, eat, drink, have a good time." But God said to him, "Fool! This very night the demand will be made for your soul; and this hoard of yours, whose will it be then?" So it is when someone stores up treasure for himself instead of becoming rich in the sight of God.'
[NJB (1985)]

Then Jesus said to them, “Watch out! Guard yourself against all kinds of greed. After all, one’s life isn’t determined by one’s possessions, even when someone is very wealthy.”
Then he told them a parable: “A certain rich man’s land produced a bountiful crop. He said to himself, What will I do? I have no place to store my harvest! Then he thought, Here’s what I’ll do. I’ll tear down my barns and build bigger ones. That’s where I’ll store all my grain and goods. 19 I’ll say to myself, You have stored up plenty of goods, enough for several years. Take it easy! Eat, drink, and enjoy yourself.
"But God said to him, ‘Fool, tonight you will die. Now who will get the things you have prepared for yourself?’ This is the way it will be for those who hoard things for themselves and aren’t rich toward God.”
[CEB (2011)]

And he said to them, “Take care! Be on your guard against all kinds of greed, for one’s life does not consist in the abundance of possessions.”
Then he told them a parable: “The land of a rich man produced abundantly. And he thought to himself, ‘What should I do, for I have no place to store my crops?’ Then he said, ‘I will do this: I will pull down my barns and build larger ones, and there I will store all my grain and my goods. And I will say to my soul, Soul, you have ample goods laid up for many years; relax, eat, drink, be merry.’
"But God said to him, ‘You fool! This very night your life is being demanded of you. And the things you have prepared, whose will they be?’ So it is with those who store up treasures for themselves but are not rich toward God.”
