'Shadows' in the Bible

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

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

Prepare ye war against her; arise, and let us go up at noon. Woe unto us! for the day declineth, for the shadows of the evening are stretched out.
