'Shadows' in the Bible

Until the day dawn, and the shadows flee away. Turn, my beloved: be thou like a gazelle or a young hart, Upon the mountains of Bether.

Until the day dawn, and the shadows flee away, I will get me to the mountain of myrrh, And to the hill of frankincense.

Prepare war against her. Arise, and let us go up at noon. Woe unto us! for the day hath declined, for the shadows of the evening are lengthening.
