As a Jew would? Which Jewish group would I look to for that? The Jews didn't understand the nature of God [same as today for us all], however there are still truths that shine forward and cannot be contidicted. Sure, they argued about what exactly did God mean when he reveals himself as we.
Truth- There are 2 words for one in Hebrew. There is 'yachid' meaning only one, something that is solitary.
Then there is the word 'echad' which usaully suggests a synergy of more than one. For example 'day and night became one day', husband and wife became one flesh'.
It is the word echad which discribes Jehovah God without exception. Even 'we made man in our image, according to our likeness'. The tower of babel the Lord says 'let us go down' yet no one else goes down with him.
