Why is there an Angel in Joshua 1:1

Kickstarter Backers are starting to get their copies of Joshua in the post. Someone has asked "What was the image in the sky based upon, on the first page?"

"Now after the death of Moses the servant of Yahweh..." 

You might be thinking "What's this heresy, adding to the scriptures?!"... but no... This is the Archangel Michael (who is one of the Cherubim) and he is there because of Jude 1:9 -

"But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not himself dare to condemn him for slander but said, "The Lord rebuke you!" "

...So it's Michael standing guard over the body before this event.

Why it looks the way it does is detailed in our other blog...
