genesis 43:2 And it came to pass, when they had eaten up the corn which they had brought out of Egypt, their father said unto them, Go again, buy us a little food. - Free Bible Online

      2. their father said, . . . Go again, buy us a little food--It was no easy matter to bring Jacob to agree to the only conditions on which his sons could return to Egypt (Ge 42:15). The necessity of immediately procuring fresh supplies for the maintenance of themselves and their families overcame every other consideration and extorted his consent to Benjamin joining in a journey, which his sons entered on with mingled feelings of hope and anxiety--of hope, because having now complied with the governor's demand to bring down their youngest brother, they flattered themselves that the alleged ground of suspecting them would be removed; and of apprehension that some ill designs were meditated against them.
