'Fatted' in the Bible

Again he sent other bondmen, saying, Say to the persons invited, Behold, I have prepared my dinner; my oxen and my fatted beasts are killed, and all things ready; come to the wedding feast.

And bring hither the fatted calf, and kill it; and let us eat, and be merry:

And he said unto him, Thy brother is come; and thy father hath killed the fatted calf, because he hath received him safe and sound.

But as soon as this thy son was come, which hath devoured thy living with harlots, thou hast killed for him the fatted calf.
