I'm not sure it does. Is it not a much later (than contemporary with the bible) attachment to Israel and Judaism?
I've just googled and that doesn't really help either.
Where in the bible does it mention The Star Of David?
This seems like a good site:
https://www.jewishvirtuallibrary.org/jsource/Judaism/star.html
The "Star Of David" is not in the Bible.
The closet scripture that has David and Star in the same verse is Revelation 22:16.
There is no mention of that in the bible. It is something that has been made up by men.
