If I may make a suggestion, there is far more information about angels other than the bible. Maybe I missed the point of this page. The Koran & Talmud have more info that early Christianity left out.
How do you know that the information in the Koran and Talmud are correct? We write from a Christian perspective, believing that the only holy scriptures that can be trusted are the Old and New Testaments of the Bible. There is good evidence for divine inspiration of the Bible, but not of the two sources you cite.
That’s why we limit ourselves to Biblical information.
Thanks for writing.
