Genesis 42:19

19 if ye be peaceable, one brother of you be bound in prison; forsooth (the rest) go ye, and bear the wheat, which ye have bought, into your houses, (if ye be honest men, then one of your brothers shall be kept here in the prison; but the rest of you go, and take the corn, or the grain, which ye have bought, back to your hungry households, or your hungry families,)

Genesis 42:19 Meaning and Commentary

Genesis 42:19

If ye [be] true [men]
As you say you are: let one of your brethren be bound in the house of your prison;
agree among yourselves which of you (for one of you must) remain in prison where you are: and the rest being set at liberty, go ye, carry corn for the famine of your houses;
Joseph, though he dealt with them after this manner to get what knowledge he could of his family, and to get sight of his brother, yet was concerned for the good of them and theirs, lest they should be in extreme want through the famine, and that they might have a speedy supply of corn, was not willing to detain them any longer.

Genesis 42:19 In-Context

17 Therefore he betook them into keeping three days; (And so he put them in the prison for three days;)

18 soothly in the third day, when they were led out of prison, Joseph said, Do ye that that I said, and ye shall live, for I dread God; (and on the third day, when they were let out of the prison, Joseph said, Do ye what I said, and ye shall live, for I fear God;)

19 if ye be peaceable, one brother of you be bound in prison; forsooth (the rest) go ye, and bear the wheat, which ye have bought, into your houses, (if ye be honest men, then one of your brothers shall be kept here in the prison; but the rest of you go, and take the corn, or the grain, which ye have bought, back to your hungry households, or your hungry families,)

20 and bring ye your youngest brother to me, that I may prove your words, and ye die not. They did as he said, (and bring ye your youngest brother to me, so that you can prove your words, and then ye shall not die. And they concurred,)

21 and they spake together, Worthily we suffer these things (and they said together, We deserve to suffer these things), for we sinned against our brother, and we saw the anguish of his soul, while he prayed us, and we heard him not; therefore this tribulation cometh on us.
