'Fattened' in the Bible

Again he sent out other slaves saying, ‘Tell those who have been invited, “Behold, I have prepared my dinner; my oxen and my fattened livestock are all butchered and everything is ready; come to the wedding feast.”’

and bring the fattened calf, kill it, and let us eat and celebrate;

And he said to him, ‘Your brother has come, and your father has killed the fattened calf because he has received him back safe and sound.’

but when this son of yours came, who has devoured your wealth with prostitutes, you killed the fattened calf for him.’

You have lived luxuriously on the earth and led a life of wanton pleasure; you have fattened your hearts in a day of slaughter.
