They wanted to ask Jesus a question in order to discredit the idea that dead people will live again. One of them said to Jesus, “Teacher, Moses wrote for us Jews about situations where a man who has a wife but no children. If the man dies, his brother should marry the dead man’s widow so that she can have a child by him. People will consider that the child is the descendant of the man who died, and in that way the dead man will have descendants.
