Genesis 42:18-20

King James Version

¹⁸ And Joseph said unto them the third day, This do, and live; for I fear God:

¹⁹ 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:

²⁰ But bring your youngest brother unto me; so shall your words be verified, and ye shall not die. And they did so.
