but i do think they were knowledgable of the trinity because those verses i mentioned extracted from the torah and tenach were written by jews. i think that they denied this later through the pharisees but the trinity was again reinforced and shown to them all when jesus was baptised
i.e. god calling out from heaven, the dove settling above jesus and jesus himself. all three were present
to the jew first then the gentiles
also jesus is truly god and truly man. see 1tim 3:16
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
