'Shadows' in the Bible

Until the day is cool, and the shadows flee away, turn, my beloved, and be like a roe or a young hart on the mountains of Bether.

Until the day is cool, and the shadows flee away, I will go to the mountain of myrrh, to the hill of frankincense.

"Prepare war against her; arise, and let us go up at noon. Woe to us! For the day declines, for the shadows of the evening are stretched out.
