'Engaged' in the Bible

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."

If a virgin is engaged to a man and another man meets her in the city and has sexual relations with her,

But if the man came across the engaged woman in the field and overpowered her and raped her, then only the rapist must die.

for the man met her in the field and the engaged woman cried out, but there was no one to rescue her.

Suppose a man comes across a virgin who is not engaged and overpowers and rapes her and they are discovered.

You will be engaged to a woman and another man will rape her. You will build a house but not live in it. You will plant a vineyard but not even begin to use it.
