The English title “Deuteronomy” comes from the Greek Septuagint (LXX)1 mistranslation of “copy of this law” in 17:18 as “second law,” which was rendered Deuteronomium in the Latin version (Vulgate). The Hebrew title of the book is translated “These are the words,” from the first two Hebrew words of the book. The Hebrew title is a better description of the book since it is not a “second law,” but rather the record of Moses’ words of explanation concerning the law. Deuteronomy completes the five-part literary unit called the Pentateuch.
