Hilary of Poitiers
Catena Aurea · Matthäusevangelium 12
And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand; And if Satan east out Satan, he is divided against himself; how shall then his kingdom stand?
Otherwise; If the dæmon was driven to this division to the end that he should thus afflict the dæmons, even thus must we attribute higher power to Him who made the division than to those who are thus divided; thus the kingdom of the Devil, after this division made, is destroyed by Christ.
