Sirach 27:20LXX

18Love thy neighbour, and be joined to him with fidelity.

19But if thou discover his secrets, follow no more after him.

20For as a man that destroyeth his friend, so also is he that destroyeth the friendship of his neighbour.

21And as one that letteth a bird go out of his hand, so hast thou let thy neighbour go, and thou shalt not get him again.

22Follow after him no more, for he is gone afar off, he is fled, as a roe escaped out of the snare: because his soul is wounded.
