What metaphors are used in Men in the Sun and Other Palestinian Stories by Ghassan Kanafani?

Metaphor:

"He felt the unuttered insult wound his throat."

"Just imagine! In my own mind I compare these hundred and fifty kilometers to the path that God in the Quran promised his creatures they must cross before being directed either to Paradise or to Hell. If anyone falls he goes to Hell, and if anyone crosses safely he reaches Paradise. Here the angels are the frontier guards."
