The Ethiopian Bible is not primarily in Hebrew or Greek. Its Old Testament is a translation from the Greek Septuagint into Ge'ez, and its New Testament was translated from Greek into Ge'ez. To produce a "complete" PDF, a team of scholars would need to translate the unique Ge'ez books (like Meqabyan) into Portuguese. Most of these books have never been officially translated into Portuguese. There are English translations (e.g., R.H. Charles' translation of Enoch from 1912, which is public domain), but they are archaic.
