Hi, if I understand correctly the prophetic perfect is sometimes associated with oath formulas, especially the if-so. Isaiah 63:8 has a "surely," even though it is not the traditional oath formula. Can anybody tell me if it is possible, not if it is or is not, but if it is possible that Isaiah 63:8 is in the prophetic perfect. I am looking at Gesenius but I probably need something much more basic if you can recommend a resource on this topic.

Thanks, Gregorio
Of course the context seems to be truly speaking of the past, beginning with Abraham, Isaac and Jacob, and the captivity in Egypt, etc.
