And they have bent their tongue, as a bow, for lies and not for truth: they have strengthened themselves upon the earth: for they have proceeded from evil to evil, and me they have not known, saith the Lord.
And when Abner was returned to Hebron, Joab took him aside to the middle of the gate, to speak to him treacherously. And he stabbed him there in the groin: and he died, in revenge of the blood of Asael his brother.
And a man shall mock his brother, and they will not speak the truth: for they have taught their tongue to speak lies, they have laboured to commit iniquity.
Let every man take heed of his neighbour, and let him not trust in any brother of his: for every brother will utterly supplant, and every friend will walk deceitfully.
