Ben Sira 40:29

29 When a man looks to the table of another, his existence cannot be considered as life. He pollutes himself with another man's food, but a man who is intelligent and well instructed guards against that.

Ben Sira 40:29 In-Context

27 The fear of the Lord is like a garden of blessing, and covers a man better than any glory.

28 My son, do not lead the life of a beggar; it is better to die than to beg.

29 When a man looks to the table of another, his existence cannot be considered as life. He pollutes himself with another man's food, but a man who is intelligent and well instructed guards against that.

30 In the mouth of the shameless begging is sweet, but in his stomach a fire is kindled.
