'Secretly' in the Bible

And Jacob deceived Laban the Aramean (Syrian) by not telling him that he intended to leave and he slipped away secretly.

Why did you run away secretly and deceive me and not tell me, so that [otherwise] I might have sent you away with joy and with songs, with [music on the] tambourine and lyre?

Joseph remembered the dreams he had dreamed about them, and said to them, “You are spies; you have come [with a malicious purpose] to observe the undefended parts of our land.”
