'Shadow' in the Bible

All the birds of the sky made their nests in its boughs; and under its branches did all the animals of the field bring forth their young; and under its shadow lived all great nations.

Strangers, the terrible of the nations, have cut him off, and have left him: on the mountains and in all the valleys his branches are fallen, and his boughs are broken by all the watercourses of the land; and all the peoples of the earth are gone down from his shadow, and have left him.

They also went down into Sheol with him to those who are slain by the sword; yes, those who were his arm, [that] lived under his shadow in the midst of the nations.
