'Shrewdly' in the Bible

Come, let us deal shrewdly with them, so that they will not multiply and in the event of war, join our enemies, and fight against us and escape from the land.”

And his master commended the unjust manager [not for his misdeeds, but] because he had acted shrewdly [by preparing for his future unemployment]; for the sons of this age [the non-believers] are shrewder in relation to their own kind [that is, to the ways of the secular world] than are the sons of light [the believers].
