it speaks deceitfully;
with his mouth each speaks peace to his neighbor,
but in his heart he plans an ambush for him.

qtheir throat is an ropen grave;
they flatter with their tongue.

2 Everyone utters lies to his neighbor;
with flattering lips and a double heart they speak.
Psalm 55:21
21 His speech was smooth as butter,
fyet war was in his heart;
ghis words were softer than oil,
yet they were drawn swords.
Psalm 62:4
4 They only plan to thrust him down from his high position.
They take pleasure in falsehood.
They bless with their mouths,
sbut inwardly they curse. Selah
