ترجمه - لاتین-انگلیسی - Vexilla Regis Prodeunt

Stanzas 2, 7 and 8 of the original version of a classical hymn made for the True Cross.

I'd prefer the translation in american or british english, although it is not very important.
My preference for brazilian portuguese would be because I am brazilian (wrote everything in english for more accessibility).
