The most comprehensive books on numerology that I have read are by Matthew Goodwin. I think his 2-volume set is great. Here is link to the first of the two. (Sorry for the sloppy link but I am on my phone.)

She compares a bunch of different meanings provided by various people, explains the history and the uses, and generally gives you the clearest foundation.

I have found this book very useful to read on that subject. I haven't finished it though, but it's very detailed https://www.amazon.com/Oracles-Apollo-Practical-Ancient-Divination-ebook/dp/B01LYUJQNX/ref=sr_1_1?keywords=greek+divination&qid=1572121667&sr=8-1

It's unfortunately out of print, but can still be found. Raymond Buckland is coming on my show Friday the 24th, I'm going to ask him if there is any chance of getting another printing going!

Also, you might check Wikipedia references on the subject. They may surprise you.
