How does John Steinbeck use imagery in In Dubious Battle?

Imagery:

The fires of hell.....

“The red light mushroomed out behind the trees. It was more than a glow now. A lance of flame cleared the tree-tops. Above the sound of steps there was a vicious crackling. From ahead came shrill cries and a muffled howling. The trees threw shadows away from the light.”

Biblical Imagery...

“He dragged Jim across the boards and leaned him against the corner post, and steadied him when he slipped sideways. London handed the lantern up, and Mac set it carefully on the floor, beside the body, so that its light fell on the head.”
