'Discerned' in the Bible

And he discerned him not, because his hands were hairy, as his brother Esau's hands: so he blessed him.

And he hasted, and took the ashes away from his face; and the king of Israel discerned him that he was of the prophets.

And beheld among the simple ones, I discerned among the youths, a young man void of understanding,

But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
