What are three examples of Perseverance in the text?

The silver sword has finally, it seems, brought about the desired reunion of the family members. Jan proudly boasts, “If I’d lost the sword, we should never have found you again” (182). Just like Ruth mused when Jan made a comment about Edek dying and finding their parents becoming impossible due to the sword’s absence, it is possible for readers to wonder one last time if the silver sword was perhaps imbued with some sort of magic or luck. Of course, even if it is, that does not negate the perseverance, struggles, and courage of the Balicki children and Jan, but it’s hard to ignore that the sword ends up being the primary thing to help connect the children to their parents and bring about their reunion.
