8:18: Persons who, within themselves, are really enemies often come garbed as friends, and among these are the following. He who takes little care to hide his intentions to rob or violate and does it brazenfaced, he who gives a little with the intention of getting much back in return; he who puts on a friendly front out of fear and he who acts friendly to serve his own ends.
8:19: The man with the well greased, mobile tongue can be distinguished in this manner. He is inclined to talk much about himself and his past accomplishments, or he will fill your ears with boasts about his future deeds; he assails your ears with empty words and with the sweet draught of flattery. Walk warily, for these are false-fronted friends and when their friendship is put to the test, it falls apart like rotten wood. When called upon for assistance in time of need they plead their own misfortunes and handicaps as excuses for standing aside.
8:20: The smooth-tongued hypocrite glosses over the misdeeds of others. He excuses unworthiness and sings your praises before your face, in your hearing, but reviles you behind your back. Avoid all such as these, for their friendship is worthless. - The Kolbrin Bible (The Celtic Texts of the Coelbook – Britain Book: Chapter Eight)
