Their tongue is a deadly arrow; it speaks deceitfully; with his mouth each speaks peaceably to his neighbor, but in his heart he plans an ambush for him.
And when Abner returned to Hebron, Joab took him aside into the midst of the gate to speak with him privately, and there he smote him in the belly, so that he died, for the blood of Asahel his brother.
They bend their tongue like a bow; falsehood and not truth has grown strong in the land; for they proceed from evil to evil, and they do not know me, says the Lord.
Let every one beware of his neighbor, and put no trust in any brother; for every brother is a supplanter, and every neighbor goes about as a slanderer.
Every one deceives his neighbor, and no one speaks the truth; they have taught their tongue to speak lies; they commit iniquity and are too weary to repent.
