+[^3]: σε：有些抄本寫成「με 我」(和合本、新譯本)，比較能延續上文 (7:25)；但 UBS5 認為「σε 你」比較可能，列在 B 等級。
 [^4]: τοῦ νόμου τῆς ἁμαρτίας ...： 罪和死的律 (7:25 罪的律)，對比於 8:2a τοῦ νόμου (聖靈之生命的律 = 7:25 神的律 )。
 [^5]: ἀδύνατον：詞形代碼有兩種可能 (ASN、NSN)，在此當作 NSN 理解的話，8:3a 就是文法上的 nominative absolute (獨立主格)，也可說是 anacoluthon (破格 = 不合文法)，有當作標題、吸引讀者注意的效果。ἀδύνατον 用中性單數，代表「事物、概念」，所以翻譯成「有所不能行的」(和合本)、「作不到的」(新譯本)。
 [^6]: τοῦ νόμου：應該是指 Torah (摩西律法)。
