'Dawn' in the Bible

To the law and to the testimony! If they do not speak according to this word, it is because they have no dawn.

“How you have fallen from heaven,O star of the morning, son of the dawn!You have been cut down to the earth,You who have weakened the nations!

Your dead will live;Their corpses will rise.You who lie in the dust, awake and shout for joy,For your dew is as the dew of the dawn,And the earth will give birth to the departed spirits.

“Then your light will break out like the dawn,And your recovery will speedily spring forth;And your righteousness will go before you;The glory of the Lord will be your rear guard.
