Psalm 55:20-22

New Century Version

²⁰ The one who was my friend attacks his friends
    and breaks his promises.
²¹ His words are slippery like butter,
    but war is in his heart.
His words are smoother than oil,
    but they cut like knives.

²² Give your worries to the Lord,
    and he will take care of you.
    He will never let good people down.
