Augustine of Hippo

"For if an enemy had upbraided me" [Psalm 55:12]. And indeed above he was "troubled in his exercise" by the voice of the enemy and by the tribulation of the sinner, perhaps being placed in that city, that proud city that was building a tower, which was "sunk," that divided might be the tongues: give heed to his inward groaning because of perils from false brethren. "For if an enemy had upbraided me, I would have undergone it assuredly, and if he that did hate me had over me spoken great words," that is, through pride had on me trampled, did magnify himself above me, did threaten me all in his power: "I would hide myself assuredly from him." From him that is abroad, you would hide yourself where? Amid those that are within. But now see whether anything else remains, but that thou seek solitude.
