Hebrews 11:35 shows us that the normative Christian Old Testament included Second Maccabees. Moreover, it shows us something else. The Protestant Old Testament begins with the book of Genesis and ends with Malachi (Modern rabbinical Bibles end with Second Chronicles). The inclusion of Second Maccabees, in the context of chapter 11, shows that the author of the Letter to the Hebrews' understood the Bible to begin with Genesis (Hebrews 11:4-22) and ended with Second Maccabees (Hebrews 11:35), and this corresponds to the first and last books of the Catholic Bible.
