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.
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.
