Genesis 43:13

Take also your brother, and arise, go again unto the man:

The command belongs to the famine that drove Jacob's sons to Egypt to buy grain. On the first journey Benjamin was not with them, and they told the Egyptian ruler that their youngest brother remained with their father. Pressing hunger and the desperate need of the family and households for food made another journey necessary and finally compelled Jacob to let Benjamin go. The ruler had solemnly required Benjamin's presence and would not receive them without him.

Judah insisted they could not go without Benjamin and pledged himself as surety for him, to bear the blame forever if he did not bring him back. Their lingering had already wasted time enough for a journey to Egypt and back. Jacob then finally consented and commanded them to take Benjamin and arise and go again to the man in Egypt, sending them on a doubtful journey. With Benjamin he sent a present for the ruler in hope of gaining favor, and double money to return the money found in their sacks in case it had been placed there by mistake, which the sons took in hand.

Before they left, Jacob stood in their midst, raised his hands to heaven, entreated the Lord to go with them, and pronounced a benediction praying that God Almighty would give them mercy before the man so that he would send away Simeon and Benjamin, resigning himself to bereavement if he must be bereaved. The sons obeyed by rising up, going down to Egypt with Benjamin and the present and double money, and standing before Joseph.
