Final answer:
Simeon is the brother who is held hostage in Egypt while Joseph's other brothers return to Canaan to fetch Benjamin.
Step-by-step explanation:
In the biblical account from the book of Genesis, Joseph's brothers return to Canaan to fetch Benjamin after Simeon is held hostage in Egypt. This event unfolds when Joseph, who is the vizier of Egypt at this time, demands that his brothers bring their youngest brother, Benjamin, to prove that they were honest men and not spies. It's important to note that the biblical stories about Joseph and his family's time in Egypt, as well as their subsequent experiences, form a part of the religious texts and tradition, rather than being verified historical facts.
