Or perhaps Moses wrote on tablets of clay like those used by the great empires of Babylon and Assyria, and by the people of Canaan. Clay was cheap enough; all one had to do was to mould moist clay into a smooth tablet, and then to prick words on it with a metal pen. The prophet Jeremiah mentions this kind of book also. (Jeremiah xvii. 1.) Most likely, however, Moses wrote on parchment made from the skins of sheep and goats. The Children of Israel kept large flocks, and could supply him with as many skins as he wanted. And in what language did he write? Perhaps even the very first words were written in Hebrew; we know that in later times the prophets and historians of the Jews wrote in Hebrew. But we must remember that languages alter as years pass on. The Hebrew of Moses' time could only have been an ancient kind of Hebrew, very different from the Hebrew of to-day. Does this surprise you? Why, you and I could hardly read one word of the English written in England even a thousand years ago! About the middle of the last century a German missionary found a large carved stone in that part of Palestine which used to be called Moab. This wonderful stone, which is black and shaped something like a tombstone, is covered with writing. It is called 'The Moabite Stone,' and was set up by Mesha, king of Moab. (2 Kings iii. 4.) The writing on it is neither Egyptian nor cuneiform, but a very ancient kind of Hebrew. [Illustration: First words of Kin Mesha's writing on the Moabite Stone. Moses most likely used letters like these] Of course, this does not take us back actually to the days of Moses, but still it is so old that Moses may well have used the same kind of writing. We have seen that most nations in those old times had their books, and we know that each nation had always one book that it valued more than the rest. This was the book that told the people about their religion, and the gods in whom they believed. In most of these books some grains of truth were found. All the nations of the world are but one great family, you know, and even the most ignorant people were not without some knowledge. The heathen nations of Moses' time therefore remembered dimly some of God's dealings with the world; they were so blinded by their heathen worship, that no atom of fresh light could reach them, and little by little they drifted further into the darkness. But, though tiny fragments of truth are to be found in their books, not one word is to be traced in any book of the most precious truth of all until God revealed it to His servant Moses. This makes our Bible so wonderful and different from all other books: it is a revelation--that is, something which comes to us from God and which we could never have known without His help. From first to last the Bible is written to teach us about Christ. Throughout the whole of the Old Testament Christ is referred to as the coming Saviour, or Messiah, which you know, is the Hebrew word for Christ.
