This is going down a branch from the tree, but the bible says explicitly and specifically that the Father is God, the Holy Ghost is God and Jesus is God. Clear and explicit.
Yachid and Echad
These are the 2 words for 'one' in Hebrew.
Why 2 words for one? Because languages do not always translate into other cultures' vocabularies.
There is the singular one that we all know in the English language and there is a plural 'one' in Hebrew that indicates the combining of things to create a [plural] one.
DIrect and explicit examples in the OT include
'Day and night became one [plural one] day'. 'Husband and Wife became one [plural] flesh' AND every instance where God is declared as One God in Hebrew it is with the plural 'one' . Clearly the OT is filled with explicit truths regarding God as more than the solitary 'oneness' that unitarians like JWs promote.
Also worth mentioning that Jew believe that God is their savior AND that he will come in the flesh. They just don't believe that Jesus was the Savior.
