Genesis 42:18-20

New King James Version

¹⁸ Then Joseph said to them the third day, “Do this and live, ^(A)for I fear God: ¹⁹ If you are honest men, let one of your brothers be confined to your prison house; but you, go and carry grain for the famine of your houses. ²⁰ And ^(B)bring your youngest brother to me; so your words will be verified, and you shall not die.”

And they did so.
