Genesis 44:7 Meaning

5Is not this it in which my lord drinketh, and whereby indeed he divineth? ye have done evil in so doing.

6And he overtook them, and he spake unto them these same words.

7And they said unto him, Wherefore saith my lord these words? God forbid that thy servants should do according to this thing:

8Behold, the money, which we found in our sacks' mouths, we brought again unto thee out of the land of Canaan: how then should we steal out of thy lord's house silver or gold?

9With whomsoever of thy servants it be found, both let him die, and we also will be my lord's bondmen.
