'Day' in the Bible

Till the day doth break forth, And the shadows have fled away, Turn, be like, my beloved, To a roe, or to a young one of the harts, On the mountains of separation!

Go forth, and look, ye daughters of Zion, On king Solomon, with the crown, With which his mother crowned him, In the day of his espousals, And in the day of the joy of his heart!

Till the day doth break forth, And the shadows have fled away, I will get me unto the mountain of myrrh, And unto the hill of frankincense.

We have a little sister, and breasts she hath not, What do we do for our sister, In the day that it is told of her?
