Book 1 · Section 3

(3) When, therefore, Moses says, "God completed his works on the sixth day," we must understand that he is speaking not of a number of days, but that he takes six as a perfect number. Since it is the first number which is equal in its parts, in the half, and the third and sixth parts, and since it is produced by the multiplication of two unequal factors, two and three. And the numbers two and three exceed the incorporeality which exists in the unit; because the number two is an image of matter being divided into two parts and dissected like matter. And the number three is an image of a solid body, because a solid can be divided according to a threefold division. (4) Not but what it is also akin to the motions of organic animals. For an organic body is naturally capable of motion in six directions, forward, backwards, upwards, downwards, to the right, and to the left. And at all events he desires to show that the races of mortal, and also of all the immortal beings, exist according to their appropriate numbers; measuring mortal beings, as I have said, by the number six, and the blessed and immortal beings by the number seven. (5) First, therefore, having desisted from the creation of mortal creatures on the seventh day, he began the formation of other and more divine beings.

III. For God never ceases from making something or other; but, as it is the property of fire to burn, and of snow to chill, so also it is the property of God to be creating. And much more so, in proportion as he himself is to all other beings the author of their working. (6) Therefore the expression, "he caused to rest," is very appropriately employed here, not "he rested." For he makes things to rest which appear to be producing others, but which in reality do not effect anything; but he himself never ceases from creating. On which account Moses says, "He caused to rest the things which he had begun." For all the things that are made by our arts when completed stand still and remain; but all those which are accomplished by the knowledge of God are moved at subsequent times. For their ends are the beginnings of other things; as, for instance, the end of day is the beginning of night. And in the same way we must look upon months and years when they come to an end as the beginning of those which are just about to follow them. (7) And so the generation of other things which are destroyed, and the destruction of others which are generated is completed, so that that is true which is said that--
