I agree, The Evolution from basic anthropomorphising of gods to a more "abstract metaphoric sense" is plain to see as you outline.
Prof. Francesca Stavrakopoulou , in her excellent, entertaining, and frankly hilarious in places Book, "God an Anatomy" * traces this evolution, and she often quotes what the best Hebrew translation of many Scriptures is, where later Bible Writers obscure the original meaning, and even Translators have tried to obscure what was said.
She comments on the "Finger of God " engraving upon the tablets that god gave to Moses, as verse Exodus 32 v 16 says, thus " As Yahweh's fingertip crafts the commandments by which his worshippers are to live, he inscribes his physical presence in to the covenant with his people".
So the simple idea of a god with fingers quickly came to have a deeper meaning.
* I recommend Prof. Stavrakopoulou's Book, if you haven't read it P.P. and to others on here, it really opens ones eyes to so much that is hidden in Scripture, much of it being the real Sexy bits, sanitised by a number of later hands !
