'Fattened' in the Bible

Saul and the people spared Agag and the best of the sheep and cattle the fattened animals and lambs along with all that was good. They were not willing to completely destroy them, but they did completely destroy everything that was worthless and inferior.

Both his servants and the woman urged him, and so he listened to them. He got up off the ground and sat on the bed. The woman had a fattened calf in the house, and she quickly slaughtered it. She took flour, kneaded it, and baked unleavened bread.
