Genesis 42:33-34

Brenton(i) 33 And the man, the lord of the land, said to us, Herein shall I know that ye are peaceable; leave one brother here with me, and having taken the corn ye have purchased for your family, depart. 34 And bring to me your younger brother; then I shall know that ye are not spies, but that ye are men of peace: and I will restore you your brother, and ye shall trade in the land.
