'Though' in the Bible

Though Edom says, “We have been beaten down, but we will return and build up the ruins”; thus says the Lord of hosts, “They may build, but I will tear down; and men will call them the wicked territory, and the people toward whom the Lord is indignant forever.”

Yet you say, ‘For what reason?’ Because the Lord has been a witness between you and the wife of your youth, against whom you have dealt treacherously, though she is your companion and your wife by covenant.
