Genesis 42:20

But bring your youngest brother unto me,.... Upon their return for more corn:

so shall your words be verified; that they were true men, and had no ill design upon the land, but were come only to buy corn:

and ye shall not die; as spies, which they were otherwise threatened with; and as it is customary in all nations to put such to death when found out:

and they did so; they left one of their brethren behind; they carried corn to their houses or families in Canaan, and brought their brother Benjamin with them when they returned to Egypt.
