While there are Scriptures that can link Yahweh and Yahshua being as one, three are no Scriptures that say there are 3 in 1 (trinity)
1 Yahchanan (John) 5:7-8 -
Verses 5:7-8 -- In the King James Version and later renditions of the Latin Vulgate, the received Greek and Latin texts include the words: “ ...In heaven, the Father, the Word, and the Holy Ghost, and these three are one. And there are three that bear witness in earth... ”. This text concerning the heavenly witness is not contained in any authentic Greek manuscript written earlier than the Fifteenth Century of this current era. It does not appear in any of the oldest Greek manuscripts; neither does it even appear in the earliest Latin translations. This text is not cited by any of the Greek or early Latin writers, even when the subject they wrote of would naturally have led them to appeal to its authority. The Emphatic Diaglott by Benjamin Wilson, Page 803, The Jerusalem Bible, New Testament, Page 419. Other scholars and researchers have frankly admitted that these words are a deliberate forgery that was never a part of the original inspired Holy Scriptures.
