The Book of the Cave of Treasures 23

1And God said unto Noah, “ Make for thyself an ark for the saving of the children of thy house, and build it [in the plain] below [this mountain], in the encampment of the children of Cain, and ye shall cut down the timber for the same [from the trees that are on] this mountain. And thus shall be the dimensions thereof. Its length shall be three hundred cubits according to thy cubit, its breadth shall be fifty cubits, and its height thirty cubits; and above it shall be finished off one cubit. And make three storeys in it: the lowermost shall be for wild animals and cattle, the middle one shall be for the birds and feathered fowl, and the topmost shall be for thee and the children of thy house. And make in it cisterns for water and cupboards for food. And make to thyself a striking board of eshkar‘a wood which will not rot, three cubits long and a cubit and a half in breadth; and there shall be a hammer of the same kind of wood, and with it thou shalt strike [the board] three times in the day. Once in the morning that the workmen may be gathered together for the work of the ark, and once at midday that they may eat food, and once at sunset so that they may cease from their labour. And when thou strikest the board, and men hear the sound of the blows, and say unto thee, ‘ What is this that thou doest?’, thou shalt say unto © them, ‘ God is going to make a flood of waters.’.”’ And Noah did as God commanded him. And there were born unto him three sons within the space of a hundred years, Shem, Ham, and Japhet, and they took unto them wives of the daughters of Methuselah.
