Charles Ellicott Commentary Luke 11:17

"But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house [divided] against a house falleth." — Luke 11:17 (ASV)

But he, knowing their thoughts.—Saint Luke seems here to bring together into one narrative two incidents which in Saint Matthew (Matthew 9:32; Matthew 12:22) appear as separated. The points of resemblance, the dumbness in both cases, both followed by the whisper that Jesus cast out devils by Beelzebub, may have easily led one who collected the facts some years after they occurred to regard the two as identical. On the general tenor of the passage, see Notes on Matthew 12:24-30.
