Sirach 29:19LXX

17It shall fight for thee against thy enemy.

18A good man is surety for his neighbour: and he that hath lost shame, will leave him to himself.

19Forget not the kindness of thy surety: for he hath given his life for thee.

20The sinner and the unclean fleeth from his surety.

21A sinner attributeth to himself the goods of his surety: and he that is of an unthankful mind will leave him that delivered him.
