Matthew 12:30

“He that is not with me, is against me, etc.] These words chiefly refer to Satan, and are a further proof, that Christ did not cast out devils by him; since they two are as much opposites, as can possibly be; Satan is not on the side of Christ, but an adversary to him; there is an original, and implacable enmity, between the serpent and the seed of the woman; there is an open war between them, and therefore one cannot be thought to lend assistance to the other.
