Noah endeavored to inculcate the ordinances and the commands known to him upon his children and his children's children. In particular he admonished them against the fornication, the uncleanness, and all the iniquity which had brought the flood down upon the earth. He reproached them with living apart from one another, and with their jealousies, for he feared that, after his death, they might go so far as to shed human blood.
Against this he warned them impressively, that they be not annihilated from the earth like those that went before. Another law which he enjoined upon them, to observe it, was the law ordaining that the fruit of a tree shall not be used the first three years it bears, and even in the fourth year it shall be the portion of the priests alone, after a part thereof has been offered upon the altar of God.
And having made an end of giving his teachings and injunctions, Noah said: "For thus did Enoch, your ancestor, exhort his son Methuselah, and Methuselah his son Lamech, and Lamech delivered all unto me as his father had bidden him, and now I do exhort you, my children, as Enoch exhorted his son. When he lived, in his generation, which was the seventh generation of man, he commanded it and testified it unto his children and his children's children, until the day of his death."
