Genesis 42:8; Genesis 42:18–20

And Joseph recognized his brothers, but they did not recognize him.


18 On the third day Joseph said to them, Do this and you will live, vfor I fear God: 19 if you are honest men, let one of your brothers remain confined where you are in custody, and let the rest go and carry wgrain for the famine of your households, 20 and xbring your youngest brother to me. So your words will be verified, and you shall not die. And they did so.
