Verse 36

And on the third day Joseph had them brought out of the ward, and he said unto them, Do this for yourselves if you be true men, so that you may live, one of your brethren shall be confined in the ward whilst you go and take home the corn for your household to the land of Canaan, and fetch your youngest brother, and bring him here unto me, that I may know that you are true men when you do this thing.
