Luke 11:18

18 If Satan is at war with himself, how will his kingdom endure? I ask this because you say that I throw out demons by the authority of Beelzebul.

Luke 11:18 Meaning and Commentary

Luke 11:18

And if Satan also be divided against himself, how shall
his kingdom stand?
&c.] This is the accommodation of the above parables, or proverbial sentences; suggesting, that Satan must be against himself, if what the Pharisees said was true; and consequently, his kingdom and government, could not long subsist:

because ye say that I cast out devils through Beelzebub;
which is all one as to say, that Satan is divided against himself, which is not reasonable to suppose; (See Gill on Matthew 12:26) and (See Gill on Mark 3:26).

17 Because Jesus knew what they were thinking, he said to them, “Every kingdom involved in civil war becomes a wasteland, and a house torn apart by divisions will collapse.

18 If Satan is at war with himself, how will his kingdom endure? I ask this because you say that I throw out demons by the authority of Beelzebul.

19 If I throw out demons by the authority of Beelzebul, then by whose authority do your followers throw them out? Therefore, they will be your judges.

20 But if I throw out demons by the power of God, then God's kingdom has already overtaken you.
