'Guile' in the Bible

Jesus saw Nathanael coming toward Him, and said of him, “Here is an Israelite indeed [a true descendant of Jacob], in whom there is no guile nor deceit nor duplicity!”

He committed no sin, nor was deceit ever found in His mouth.

For,“The one who wants to enjoy life and see good days [good—whether apparent or not],Must keep his tongue free from evil and his lips from speaking guile (treachery, deceit).
