Where do I start learning the Bible, as someone coming from a non-western background?

I live in Nepal. I have no background in any of the Abrahamic religions. I want to study the Bible in simple language with the aid of a book that provides context and spiritual meanings. By "simple" I do not mean simple English. My English is very good. I want a proper explanation of the use of metaphors, myths, etc. in the Bible The book also needs to be suitable for self study. I already have the [Thomas Nelson KJV Study Bible](https://www.thomasnelsonbibles.com/product/the-king-james-study-bible-full-color-kjv/) . **Example**: I am right now on the book of Genesis. I was reading the passage about the fight between the Serpent and Eve. There is a verse (Gen 3:15) that says something like he will strike heels and she his head. I want to know if there is any spiritual metaphor here, or whether I am missing something. These are the kind of questions I have that I hope the study aid can answer.
