'Sit in Darkness' in the Bible

Such as sit in darkness and in the shadow of death, being bound in affliction and iron;

To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house.

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.

To give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace.
