The best that I can do is come up with some options. I've sung Latin before, but that's the extent of my experience. So, here are some ideas:
Pater musta rigen ergo mit entricto mia fratriste
Father stiff, therefore, must send Mia entricto fratriste
Pater musta regen ergo mit entrivo mia fratri iste
Therefore, this ruling must send his brother Father entrivo Mia
Pater musta rigen ergo mit entrido mia frater iste
The Father must be steadfast; therefore, he must send to his brother... mia entrido.
Pater musta rigen ergo mit entrivo mia fra triste
Father stiff, therefore, must send Mia brethren sad entrivo
Maybe this will spark inspiration.
Hope it helps! (4 years later)
