Then by the Lord of the heaven and earth, indeed, it is truth - just as [sure as] it is that you are speaking.

By the Lord of the heavens and earth! All this is as real as your speaking.

Then by the Lord of the heaven and the earth, it is the truth (i.e. what has been promised to you), just as it is the truth that you can speak.
