And I will make Jerusalem a heap of ruins, and a den of jackals; and I will make the cities of Judah desolate, without an inhabitant.
All Commentaries on Jeremiah 9:11 Go To Jeremiah 9
Cyril of Alexandria

A most base pest, my beloved, is double dealing and hypocrisy in our actions and conduct, by which a person uses the pretense of pleasant-spoken words and of a tongue anointed, so to speak, with the honey of deception, while the heart is full of utter bitterness. Of such we say, in the words of one of the holy prophets, “Their tongue is a piercing arrow; the words of their mouth are deceitful. He speaks peacefully to his neighbor, and enmity is in his heart.” And again, “Their words are smoother than oil, yet are they arrows.” By which is meant that they have the force of darts falling violently and shot forth from bows.
