'Death shade' in the Bible

Let darkness and death-shade buy it back, May there settle down upon it a cloud, Let a day's dark eclipse cause it terror:

Before I go, and not return, unto a land of darkness and death-shade:

A land of obscurity, like thick darkness, of death-shade and disorder, and which shineth like thick darkness.

Laying open deep things, out of darkness, and bringing out to light, the death-shade:

My face, is reddened from weeping, and, upon mine eyelashes, is the death-shade: -

For, in the case of all such, morning to them is the death-shade, For, to be recognised, is a death-shade terror.

An end, hath one set to the darkness, and, into every extremity, is, he, making search, for the stone of darkness and death-shade;

No darkness, and no death-shade, where the workers of iniquity may hide.

Have the gates of death been disclosed to thee? And, the gates of the death-shade, couldst thou descry?

The dwellers in darkness and death-shade, bound with oppression and iron;

He brought them forth out of darkness and death-shade, and, their fetters, he tare off.

Neither said they, Where is Yahweh, Who brought us up out of the land of Egypt, - Who led us Through the desert, Through a land of wastes and clefts, Through a land of parched places and of death-shade, Through a land, Along which no man had passed, And in which no son of earth dwelt?
