Sirach 4:1-6

1 My son, defraud not the poor of his living, and make not the needy eyes to wait long.
2 Make not an hungry soul sorrowful; neither provoke a man in his distress.
3 Add not more trouble to an heart that is vexed; and defer not to give to him that is in need.
4 Reject not the supplication of the afflicted; neither turn away thy face from a poor man.
5 Turn not away thine eye from the needy, and give him none occasion to curse thee:
6 For if he curse thee in the bitterness of his soul, his prayer shall be heard of him that made him.
