Genesis 42:18-20

Young's Literal Translation

¹⁸ And Joseph saith unto them on the third day, `This do and live; God I fear!

¹⁹ if ye [are] right men, let one of your brethren be bound in the house of your ward, and ye, go, carry in corn [for] the famine of your houses,

²⁰ and your young brother ye bring unto me, and your words are established, and ye die not;' and they do so.
