Proverbs 26:26-28

Amplified Bible

²⁶ 
Though his hatred covers itself with guile and deceit,
His malevolence will be revealed openly before the assembly.
²⁷ 
Whoever digs a pit [for another man’s feet] will fall into it,
And he who rolls a stone [up a hill to do mischief], it will come back on him.^(A)
28 
A lying tongue hates those it wounds and crushes,
And a flattering mouth works ruin.
