The art of writing is not mentioned in the Bible prior to the time of Moses, although as before stated, in Egypt and the countries adjacent thereto it was not only known but practiced.

Its first mention recorded in Scripture will be found in Exodus xvii. v. 14; "And the Lord said unto Moses, Write this, for a memorial, in a book; and rehearse it in the ear of Joshua; for I will utterly put out the remembrance of Amalek from under heaven." This command was given immediately after the defeat of the Amalekites near Horeb, and before the arrival of the Israelites at Mount Sinai.

It is observable, that there is not the least hint to induce us to believe that writing was then newly invented; on the contrary, we may conclude, that Moses understood what was meant by writing in a book; otherwise God would have instructed him, as he had done Noah in building the Ark; for he would not have been commanded to write in a book, if he had been ignorant of the art of writing; but Moses expressed no difficulty of comprehension when he received this command. We also find that Moses wrote all the works and all the judgments of the Lord, contained in the twenty-first and the two succeeding chapters of the book of Exodus, before the two written tables of stone were even so much as promised. The delivery of the tables is not mentioned till the eighteenth verse of the thirty-first chapter, after God had made an end of communing with him upon the mount, though the ten commandments were promulgated immediately after his third descent.

Moses makes frequent mention of ancient books of the Hebrews, but describes none, except the two tables on which God wrote the ten commandments. These he tells us, were of polished stone, engraven on both sides and as Calmet remarks: "it is probable that Moses would not have observed to us these two particulars so often as he does, were it not to distinguish them from other books, which were made of tables, not of stone, but of wood and curiously engraven, but on one side only."

It cannot be said that Moses uses any language which can be construed to mean the employment of rolls of papyrus, or barks of trees, much less of parchment. We have therefore reason to believe that by the term book, he always means table-books, made of small thin boards or plates.

The edicts, as well as the letters of kings, were written upon tablets and sent to the various provinces, sealed with their signets. Scripture plainly alludes to the custom of sealing up letters, edicts and the tablets on which the prophets wrote their visions.

The practice of writing upon rolls made of the barks of trees is very ancient. It is alluded to in the Book of Job: "Oh! that mine adversary had written a book; surely I would take it upon my shoulders, and bind it as a crown to me." (Old version.) The new one runs: "And that I had the indictment which mine adversary hath written!" The rolls, or volumes, generally speaking, were written upon one side only. This is intimated by Ezekiel who observes that he saw one of in extraordinary form written on both sides: "And when I looked, behold, an Hand was sent unto me, and lo! a roll of a book was therein; and he spread it before me, and it was written within and without."

To have been able to write on dry tablets of wood or barks of trees with the reed or brush, the then only ink-writing instruments in vogue would have necessitated the employment of lampblack suspended in a vehicle of thick gum, or in the form of a paint. Both of these maybe termed pigmentary inks. The use of thin inks would have caused spreading or blotting and thus rendered the writing illegible.

The Encyclopaedia Britannica generalizes its remarks on this subject:—

"The earliest writings were purely monumental and accordingly those materials were chosen which were supposed to last the longest. The same idea of perpetuity which in architecture finds its most striking exposition in the pyramids was repeated, in the case of literary records, in the two columns mentioned by Josephus, the one of stone and the other of brick, on which the children of Seth wrote their inventions and astronomical discoveries; in the pillars in Crete on which, according to Porphyry, the ceremonies of the Corybantes were inscribed; in the leaden tablets containinlu the works of Hesiod, deposited in the temple of the Muses, in Boeotia; in the ten commandments on stone delivered by Moses; and in the laws of Solon, inscribed on planks of wood. The notion of a literary production surviving the destruction of the materials on which it was first written—the 'momentum, aere perennius' of Horace's ambition—was unknown before the discovery of substances for systematic transcription.
