No. The Ethiopian Bible does not argue with Scripture. It extends it.
The books you already know are all here. Genesis to Revelation, the text you grew up with. Nothing taken out. Nothing rewritten. Nothing swapped.
Beside them sit 22 more. Enoch, Jubilees, and Meqabyan, preserved in the Ethiopian Orthodox tradition for over 1,600 years.
They do not rival the Bible you know. They open it up. They supply the context. They pick up what the shorter canon leaves hanging: the origin of the Nephilim, the centuries between the testaments, how the first believers saw the spiritual world.
Treat it as the wider library, not a second Bible. Same ground. More chapters.
You are not exchanging one Scripture for another. You are reading what stood there before the shorter set was closed.
