What does Deuteronomy 22:19 mean?

They’ll fine him a hundred pieces of silver and give it to the woman’s father, because the man tried to ruin her reputation. She’ll stay his wife, and he can’t ever divorce her. Deuteronomy 22:19 - Modern Text Bible

(The fine is both a punishment and a way to restore the woman’s honor. The man loses the right to divorce her as a further consequence.)
