'Fat' in the Bible

For this nation’s heart has grown hard,And with their ears they hardly hear,And they have [tightly] closed their eyes,Otherwise they would see with their eyes,And hear with their ears,And understand with their heart, and turn [to Me]And I would heal them [spiritually].’

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.”’
