Deuteronomy 20:7

20:7 Or who among you has become engaged to a woman but has not married her? He may go home, lest he die in battle and someone else marry her.”

Matthew 1:18-19

The Birth of Jesus Christ

1:18 Now the birth of Jesus Christ happened this way. While his mother Mary was engaged to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit. 1:19 Because Joseph, her husband to be, was a righteous man, and because he did not want to disgrace her, he intended to divorce her privately.
