'Shadow' in the Bible

Let darkness and the shadow of death claim it for their own. Let a cloud dwell on it. Let all that makes black the day terrify it.

As a servant who earnestly desires the shadow, as a hireling who looks for his wages,

(For we are but of yesterday, and know nothing, because our days on earth are a shadow.)

before I go where I shall not return from, to the land of darkness and of the shadow of death;

the land dark as midnight, of the shadow of death, without any order, where the light is as midnight.'"

He uncovers deep things out of darkness, and brings out to light the shadow of death.

He comes forth like a flower, and is cut down. He also flees like a shadow, and doesn't continue.

My eye also is dim by reason of sorrow. All my members are as a shadow.

Have the gates of death been revealed to you? Or have you seen the gates of the shadow of death?
