Dịch - Portuguese brazilian-Latinh - Ainda que eu ande pelo vale da sombra da morte;

Et si sounds like French
Latin should be etsi or etiamsi

+ con. perfecti:
etsi ambulaverim in valle umbrae mortis ...

Yours sincerely

Aneta, this is one of the official translations, I think

see the results in Mother Google

But if you want you can correct, it seems both versions are ok, although Etsi is less used and Etiamsi is almost not used in this case.

Ciaociao

Oh, you're right I think. I'm sorry. Maybe I am to much connected with standard classical Latin Thank you for your post and explanation!

Not a problem!!!
