'Day' 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.

Go forth, O ye daughters of Zion, and behold king Solomon, With the crown wherewith his mother hath crowned him In the day of his espousals, And in the day of the gladness of his heart.

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.

We have a little sister, And she hath no breasts: What shall we do for our sister In the day when she shall be spoken for?
