'Fat' in the Bible

For the heart of this people has become fat and their ears are slow in hearing and their eyes are shut; for fear that they might see with their eyes and give hearing with their ears and become wise in their hearts and be turned again to me, so that I might make them well.

Again he sent out other servants, with orders to say to the guests, See, I have made ready my feast: my oxen and my fat beasts have been put to death, and all things are ready: come to the feast.
