Psalm 144:8 in the King James Version
Whose mouth speaketh vanity, and their right hand is a right hand of falsehood.
Context
7 Stretch out your hand from above, rescue me, and deliver me out of great waters, out of the hands of foreigners,
8 whose mouths speak deceit, whose right hand is a right hand of falsehood.
9 I will sing a new song to you, God. On a ten-stringed lyre, I will sing praises to you.
