'Espousals' in the Bible

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.

Go, and cry in the ears of Jerusalem, saying, Thus saith Jehovah, I remember for thee the kindness of thy youth, the love of thine espousals; how thou wentest after me in the wilderness, in a land that was not sown.
