'Though' in the Bible

Edom says, "Though we are devastated, we will once again build the ruined places." So the Lord who rules over all responds, "They indeed may build, but I will overthrow. They will be known as the land of evil, the people with whom the Lord is permanently displeased.

Yet you ask, "Why?" The Lord is testifying against you on behalf of the wife you married when you were young, to whom you have become unfaithful even though she is your companion and wife by law.
