Actions, not words, prove our honesty

Genesis 42:10-11, 18-20

And they said unto him, Nay, my lord, but to buy food are thy servants come. We are all one man’s sons; we are true men, thy servants are no spies. And Joseph said unto them the third day, This do, and live; for I fear God: If ye be true men, let one of your brethren be bound in the house of your prison: go ye, carry corn for the famine of your houses: But bring your youngest brother unto me; so shall your words be verified, and ye shall not die. And they did so.
