'Intelligent' in the Bible

who was with the proconsul Sergius Paulus, an intelligent man. He, having called Barnabas and Saul to him, desired to hear the word of God.

I beseech you therefore, brethren, by the compassions of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your intelligent service.

I speak as to intelligent persons: do ye judge what I say.

For we dare not class ourselves or compare ourselves with some who commend themselves; but these, measuring themselves by themselves, and comparing themselves with themselves, are not intelligent.
