Mark 9:40

For he that is not against us, is on our part.
] Many copies read, "he that is not against you, is for you"; as this man; he was not against either Christ, or his disciples; he was doing the same work, promoting the same interest, and destroying the kingdom of Satan: and therefore, though he did not follow them, and had not his commission immediately from Christ; yet, inasmuch as he was opposing the same common enemy, and did nothing against them, he ought to be reckoned as one for them, and on their side. It is a proverbial expression, signifying that all that are not against a man, and take not the part of his enemy, are to be accounted his friends.
