Genesis 42:19 BBE

¹⁷  So he put them in prison for three days.

¹⁸  And on the third day Joseph said to them, Do this, if you would keep your lives: for I am a god-fearing man:

¹⁹  If you are true men, let one of you be kept in prison, while you go and take grain for the needs of your families;

²⁰  And come back to me with your youngest brother, so that your words may be seen to be true, and you will not be put to death. This is what you are to do.

²¹  And they said to one another, Truly, we did wrong to our brother, for we saw his grief of mind, and we did not give ear to his prayers; that is why this trouble has come on us.
