Don’t believe your neighbor or trust your friend. Be careful what you say even to your husband or wife. Micah 7:5

Even my best friend, the one I trusted completely, the one who shared my food, has turned against me. If an enemy were insulting me, I could endure it; if a foe were rising against me, I could hide. But it is you, a man like myself, my companion, my close friend, with whom I once enjoyed sweet fellowship at the house of God, as we walked about among the worshipers. Psalm 55
