To me, as I meditate and consider in my mind concerning the creation of this world in which we are kept enclosed, even such is the rapidity of that creation; as is contained in the book of Moses, which he wrote about its creation, and which is called Genesis. God produced that entire mass for the adornment of His majesty in six days; on the seventh to which He consecrated it . . . with a blessing. For this reason, therefore, because in the septenary number of days both heavenly and earthly things are ordered, in place of the beginning I will consider of this seventh day after the principle of all matters pertaining to the number of seven; and as far as I shall be able, I will endeavor to portray the day of the divine power to that consummation.
