'Fat' in the Bible

"Again he sent other servants with a message to those who were invited. "'My breakfast is now ready," he said, 'my bullocks and fat cattle are killed, and every preparation is made: come to the wedding.'

Fetch the fat calf and kill it, and let us feast and enjoy ourselves;

"'Your brother has come,' he replied; 'and your father has had the fat calf killed, because he has got him home safe and sound.'

but now that this son of yours is come who has eaten up your property among his bad women, you have killed the fat calf for him.'
