=5.= The word _Biblia_ was thus endowed with a special meaning in the Greek, signifying _the books_, that is to say the holy books as distinguishing the sacred scriptures from all other writings; and the term soon became current in the Latin, in which tongue it was used from the first in its special sense. Through Latin usage, perhaps during the thirteenth century, the word came to be regarded as a singular noun signifying _the book_; this departure from the plural meaning, invariably associated with the term in the Greek original, led up to the popular error of regarding the Bible as having been a unified volume from the first. Hence we meet with the reputed derivation of the word from the Greek singular noun _Biblos_ meaning _the book_, but this is declared by a preponderance of good authority to be founded on a traditional misconception. It may appear that the derivation of a word is of trifling importance; yet in this case, the original form and first use of the title now current as that of the sacred volume must be of instructive interest, as throwing some light upon the compilation of the book in its present form. =6.= It is evident that the name _Bible_ is not of itself a biblical term; its use as a designation of the Jewish scriptures is wholly external to those scriptures themselves. In its earliest application, which dates from post-apostolic times, it was made to embrace most if not all the books of the Old and the New Testament. Prior to the time of Christ, the books of the Old Testament were known by no single collective name, but were designated in groups as (1) the Pentateuch, or five books of the Law; (2) the Prophets; and (3) the Hagiographa, comprising all sacred records not included in the other divisions. But we may the better consider the parts of the Bible by taking the main divisions separately. A very natural division of the biblical record is effected by the earthly work of the Savior; the written productions of pre-Christian times came to be known as the Old Covenant; those of the days of the Savior and the years immediately following, as the New Covenant.[733] The term _testament_ gradually grew in favor until the designations Old and New Testaments became common.
