Genesis 42:19 in the King James Version
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:
Context
18 Joseph said to them the third day, “Do this, and live, for I fear God.
19 If you are honest men, then let one of your brothers be bound in your prison; but you go, carry grain for the famine of your houses.
20 Bring your youngest brother to me; so will your words be verified, and you won’t die.” They did so.
