“The entire canon of the OT was in place while Jesus walked the earth. Does this mean all believers are beholden to the Jews who were the custodians of these texts? Of course.”
Does this mean you use all the books contained in the Septuagint?
The Septuagint contains some books not found in the Hebrew Bible. These books — now referred to as the Apocrypha — were recognized even during the first few centuries AD (by such church leaders as St. Jerome) as not having the weight and authority of Scripture. Historical — kinda maybe sorta — but God’s Word? No.
