Sirach 37:1-6

1 Every friend saith, I am his friend also: but there is a friend, which is only a friend in name.
2 Is it not a grief unto death, when a companion and friend is turned to an enemy?
3 O wicked imagination, whence camest thou in to cover the earth with deceit?
4 There is a companion, which rejoiceth in the prosperity of a friend, but in the time of trouble will be against him.
5 There is a companion, which helpeth his friend for the belly, and taketh up the buckler against the enemy.
6 Forget not thy friend in thy mind, and be not unmindful of him in thy riches.
