Where are these heroes' faith "attested?" Given that (1) the chapter is recounting sacred history (concerning supernatural faith), not secular history, (2) Hebrews explicitly states three times that these men and women are "attested to" somewhere; and (3) the order given corresponds roughly to the order in which they appear in Scripture, there is little reason to doubt that the characters come from Scripture. Specifically, they come from an ancient Greek translation of the Old Testament known as the Septuagint or LXX.
