'Shadow' in the Bible

“They did not say, ‘Where is the LordWho brought us up from the land of Egypt,Who led us through the wilderness,Through a land of deserts and of pits,Through a land of drought and of the deep darkness [of the shadow of death],Through a land that no man passed throughAnd where no man lived?’

Give glory to the Lord your God,Before He brings darknessAnd before your feet stumbleOn the dark and shadowy mountains,And while you are longing for lightHe turns it into the shadow of death,And makes it into thick darkness.

“In the shadow of HeshbonThe fugitives stand powerless [helpless and without strength],For a fire has gone out from Heshbon,A flame from the midst of Sihon;It has destroyed the forehead of MoabAnd the crowns of the heads of [the arrogant Moabites] the ones in tumult.
