'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.

For the heart of this people has become fat, and they hear heavily with their ears, and they have closed their eyes; lest they should see with their eyes, and hear with their ears, and understand with their heart, and be converted, and I should heal them.
