John Gill Commentary 1 Kings 21:5

"But Jezebel his wife came to him, and said unto him, Why is thy spirit so sad, that thou eatest no bread?" — 1 Kings 21:5 (ASV)

She perceived he was low spirited, and supposed he had met with something that had ruffled him, and made him so uneasy that he could not eat his food; and she desired to know what it was, that she might relieve him if possible.
