'Fat' in the Bible

for the heart of this people has grown fat, and they have heard heavily with their ears, and they have closed their eyes as asleep, lest they should see with the eyes, and hear with the ears, and understand with the heart, and should be converted, and I should heal them.

Then he sent out some other servants, saying, ‘Tell those who have been invited, “Look, I have prepared my dinner; my oxen and fattened calves are butchered and everything is ready; come to the wedding feast.”’
