'Discern' in the Bible

And he did not discern him, because his hands were hairy, as his brother Esau's hands; and he blessed him.

With whomsoever thou findest thy gods, he shall not live. Before our brethren discern what is thine with me, and take it to thee. But Jacob did not know that Rachel had stolen them.

and they sent the vest of many colours and had it carried to their father, and said, This have we found: discern now whether it is thy son's vest or not.
