Because — This is mentioned as the reason of his insolent carriage towards God, because he was fat, rich, potent, and successful, as that expression signifies, Deuteronomy 32:15; Psalms 78:31; Jeremiah 46:21. His great prosperity made him proud and secure, and regardless of God and men. Fat — His only care is to pamper himself.
