'Appear' in the Bible

Then Jonadab said to him, "Lie down on your bed and appear ill. If your father comes to see you, you shall say to him, 'Please let Tamar my sister come and give me food to eat, and let her prepare the food before my eyes, in order that I may see it and eat from her hand.'"

With the pure, you show yourself pure, but with the crooked, you appear as a fool.
