Psalm 35:4-6

Amplified Bible

⁴ 
Let those be ashamed and dishonored who seek my life;
Let those be turned back [in defeat] and humiliated who plot evil against me.
⁵ 
Let them be [blown away] like chaff before the wind [worthless, without substance],
With the angel of the Lord driving them on.
⁶ 
Let their way be dark and slippery,
With the angel of the Lord pursuing and harassing them.
