The people which sat in darkness saw great light; and to them which sat in the region and shadow of death light is sprung up.
Such as sit in darkness and in the shadow of death, being bound in affliction and iron; Because they rebelled against the words of God, and contemned the counsel of the most High: Therefore he brought down their heart with labour; they fell down, and there was none to help. Then they cried unto the LORD in their trouble, and he saved them out of their distresses. He brought them out of darkness and the shadow of death, and brake their bands in sunder.
Rejoice not against me, O mine enemy: when I fall, I shall arise; when I sit in darkness, the LORD shall be a light unto me.
Luke 1:78-79
Through the tender mercy of our God; whereby the dayspring from on high hath visited us, To give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace.
Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
