Sirach 29:7-17

7 Many therefore have refused to lend for other men's ill dealing, fearing to be defrauded.
8 Yet have thou patience with a man in poor estate, and delay not to shew him mercy.
9 Help the poor for the commandment's sake, and turn him not away because of his poverty.
10 Lose thy money for thy brother and thy friend, and let it not rust under a stone to be lost.
11 Lay up thy treasure according to the commandments of the most High, and it shall bring thee more profit than gold.
12 Shut up alms in thy storehouses: and it shall deliver thee from all affliction.
13 It shall fight for thee against thine enemies better than a mighty shield and strong spear.
14 An honest man is surety for his neighbour: but he that is impudent will forsake him.
15 Forget not the friendship of thy surety, for he hath given his life for thee.
16 A sinner will overthrow the good estate of his surety:
17 And he that is of an unthankful mind will leave him that delivered him.
