I understand from a 1981 edition that Paul wrote Hebrews.
Not so, I understand that its style is different from Paul's letters and that early Church Fathers say that Barsabbas(sp)alias Joseph, a Levite from Cyprus(Hebrews does mention the Jerusalem temple)
I humbly suggest that the WT buys a NIV study bible and toss all those factually inaccurate sources out of the window
