Yahweh, He is God; there is no other besides Him." Deuteronomy 4:35
this passage which is repeated many times in the Old Testament does not say that there is none besides them (the trinity) but none besides the one God Yahweh. Then in the New Testament it says that Jesus and the Holy Spirit are also God. This is a contradiction. Additionally three different state of affairs cannot be the one same state of affairs, therefore, the three different persons of the trinity can not be the same god.
