Subtil

Subtle: communicating or acting in a way that is not obvious, direct, or easily noticed, often through skillful, clever, delicate, or indirect methods to convey meaning, make fine distinctions, or achieve a goal without being blatant Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? — Genesis 3:1 But Amnon had a friend, whose name was Jonadab, the son of Shimeah David’s brother: and Jonadab was a very subtil man. — 2 Samuel 13:3 And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord? — Acts 13:10 And consulted that they might take Jesus by subtilty, and kill him. — Matthew 26:4
