'Though' in the Bible

Though Edom says, We are crushed down but we will come back, building up the waste places; this is what the Lord of armies has said: They may put up buildings, but I will have them pulled down; and they will be named The land of evil-doing, and The people against whom the Lord keeps his wrath for ever.

But you say, For what reason? Because the Lord has been a witness between you and the wife of your early years, to whom you have been untrue, though she is your friend and the wife to whom you have given your word.
