New Moon is marked with the lighting of a single candle [ascending smoke offering]. And on the New Moon of the first month, and on the New Moon of the fourth month, and on the New Moon of the seventh month, and on the New Moon of the tenth month are the days of remembrance, and the days of the seasons in the four divisions of the year. These are written and ordained as a testimony forever. And Noach ordained them for himself as feasts for the generations forever, so that they have become thereby a memorial unto him. And on the New Moon of the first month he was bidden to make for himself an ark, and also on that day the earth became dry and he opened the ark and saw the earth. And on the New Moon of the fourth month the mouths of the depths of the abyss beneath were closed. And on the New Moon of the seventh month all the mouths of the abysses of the earth were opened, and the waters began to descend into them. And on the New Moon of the tenth month the tops of the mountains were seen, and Noach was glad. And on this account, he ordained them for himself as feasts for a memorial forever, and thus are they ordained. (Jubilees)
