'Schemes' in the Bible

so that we may not be exploited by Satan (for we are not ignorant of his schemes).

So we are no longer to be children, tossed back and forth by waves and carried about by every wind of teaching by the trickery of people who craftily carry out their deceitful schemes.

Clothe yourselves with the full armor of God so that you may be able to stand against the schemes of the devil.
