Good morning,
I am have a problem understanding the first part of this sentence [ in bold ]:
Atque ut inde oratio mea proficiscatur unde haec omnis causa ducitur, bellum grave et periculosum vestris vectigalibus atque sociis a duobus potentissimis adfertur regibus, Mithridate et Tigrane, quorum alter relictus, alter lacessitus occasionem sibi ad occupandam Asiam oblatam esse arbitratur.
I not entirely sure of the force of the ut governing the subjunctive verb but I guess part of my confusion is also the use of inde … unde …
I could provide a translation but it would be horrible
