'Betrothal' in the Bible

“Go and proclaim in the ears of Jerusalem, saying, ‘Thus says the Lord,“I remember [earnestly] the lovingkindness and devotion of your youth,Your time of betrothal [like that of a bride during the early years in Egypt and again at Sinai],When you followed Me in the wilderness,Through a land not sown.

But Joseph her husband, being a kind-hearted man and unwilling publicly to disgrace her, had determined to release her privately from the betrothal.
