What does Genesis 42:5 mean?

Sent by their father Jacob from the Promised Land of Canaan (Genesis 37:1), the ten oldest "sons of Israel" (Genesis 35:10) arrive in Egypt. They find themselves among the throng of travelers from many lands, all looking to buy food to help their people survive the desperate famine (Genesis 42:1–4). Their younger brother, Benjamin, has not come along. Their father believes he has lost one son to death (Genesis 37:31–34), not knowing Joseph was sold as a slave by the jealous older sons (Genesis 37:28).

One reason for the brothers' hatred of Joseph were his dreams, which predicted they would one day bow to him (Genesis 37:5–11). They don't know that the brother they hated and sold is now the governor of the entire nation of Egypt (Genesis 41:44, 56). The unlikeliest of reunions is about to take place, and each of these ten men will end up bowing in submission, just as the dreams predicted (Genesis 42:6). This will ultimately lead the entire family to come to Egypt, under the leadership of Joseph (Genesis 47:11–12).
