The Hebrew Bible: A Translation with Commentary is an English translation of the Hebrew Bible completed by Robert Alter in 2018, being written over the course of two decades.
This is a particularly interesting period in Christianity, because you had numerous influences (including what would later become gnosticism around the same time), the term "trinity" wouldn't appear in extant works until sometime in the Second Century, then the Council of Nicaea in or around the latter half of the Fourth Century establishing it as doctrine.
So, I think the evidence of a decidedly Jewish influence is quite strong and would date at least to the Babylonian captivity.
I believe Dr. Robert Alter leans toward an evolution from polytheism -> monotheism in Jewish thinking (I highly recommend his The Hebrew Bible: A Translation with Commentary); but I think the evidence for a sort of henotheism is a bit stronger and more sensible, which would better fit the sources you shared here, alongside the biblical texts.

Robert Alter's translations of the Hebrew Bible have lots of interesting notes.
From wiki: "Alter's translation aims to convey the literary style of the original Hebrew text in English, recreating as much as possible its poetic rhythms and metaphors"
I think many of the Psalms and Ecclesiastes in particular are more beautifully rendered in his translation
