Mat 12:26 And if Satan casts out Satan, he is divided against himself; how shall then his kingdom stand?

The idea of the words here is that of an adversary, which means "one opposed to another," cannot also be opposed to himself.

"Satan" is Satanas, which is an Aramaic word meaning "adversary" or "one who opposes anothers in purpose or act. " The word is used only in the New Testament. The meaning it has comes from Christian traditions unknown at the time the Gospels were written. (I plan to write about all Christ's reverences to the devil, demons, and Satan at some future date, to separate what Christ taught from Christian tradition.)

"Cast out" is ekballô, "throw out," "cast out," "throw away," "caste aside," or "strike out."

"Divided" is merizô, which means "to divide," "to spit up," and "to be divided."

"Kingdom" is basileia which "kingdom," "dominion," "royal power," and "reign."

"Stand" is histêmi, which means (among other things) "to stand," "to set up," "to place," and "to rise up." (See the last post for more about these last three words.)
