Psalms 55:12-14, 20-21 It is not an enemy who taunts me — then I could bear it; it is not an adversary who deals insolently with me — then I could hide from him.  But it is you, my equal, my companion, my familiar friend.  We used to hold sweet converse together; within God’s house we walked in fellowship. . . .  My companion stretched out his hand against his friends, he violated his covenant.  His speech was smoother than butter, yet war was in his heart; his words were softer than oil, yet they were drawn swords.

Sirach 6:8-10 For there is a friend who is such at his own convenience, but will not stand by you in your day of trouble.

Luke 12:51-53 Do you think that I have come to give peace on earth? No, I tell you, but rather division;  for henceforth in one house there will be five divided, three against two and two against three;  they will be divided, father against son and son against father, mother against daughter and daughter against her mother, mother-in-law against her daughter-in-law and daughter-in-law against her mother-in-law.
