'Schemes' in the Bible

By his treachery he will succeed through deceit. He will have an arrogant attitude, and he will destroy many who are unaware of his schemes. He will rise up against the Prince of princes, yet he will be broken apart -- but not by human agency.

In a time of tranquility he will enter the richest parts of the realm, and he will accomplish what his fathers never did, nor his ancestors; he will distribute plunder, booty and possessions among them, and he will devise his schemes against strongholds, but only for a time.

He'll encourage himself against the southern king by raising a large army. As a result, the southern king will mobilize for war with a large and powerful army, but he won't succeed because they will devise elaborate schemes against him.
