'Though' in the Bible

Though Edom says: “We have been devastated, but we will rebuild the ruins,” the Lord of Hosts says this: “They may build, but I will demolish. They will be called a wicked country and the people the Lord has cursed forever.

Yet you ask, “For what reason?” Because the Lord has been a witness between you and the wife of your youth. You have acted treacherously against her, though she was your marriage partner and your wife by covenant.
