What are the literary devices in here?

Religious Imagery:

"Bed looked very inviting. But first he got down on his knees, made the sign of the cross, and prayed for the safety of his sisters, and then for the safety of his country and the world. God show us mercy, he prayed. And give me strength. Only then did he allow himself to escape into sleep" (Chapter 1, p. 19).

Metaphor:

"It was a scene unlike any Alex could have imagined. If he looked up, it was Yankee Stadium, filled with empty seats. But if he looked at eye level, it was hell" (Chapter 3, p. 62).

Foreshadowing:

In Chapter 13, Briana is shown to not have her inhaler inhaler, and she nearly passes out, having forgotten to bring it with her. This foreshadows her death later in the novel when she is trapped in an elevator without proper medication, and perishes.
