15. Just as Jacob, again, was not the creator of the colors in the flocks, because he placed the various colored rods for the several mothers, as they drank, to look at in conceiving. Yet neither were the cattle themselves creators of the variety of their own offspring, because the variegated image, impressed through their eyes by the sight of the varied rods, clave to their soul, but could affect the body that was animated by the spirit thus affected only through sympathy with this commingling, so far as to stain with color the tender beginnings of their offspring. For that they are so affected from themselves, whether the soul from the body, or the body from the soul, arises in truth from suitable reasons, which immutably exist in that highest wisdom of God Himself, which no extent of place contains; and which, while it is itself unchangeable, yet quits not one even of those things which are changeable, because there is not one of them that is not created by itself. For it was the unchangeable and invisible reason of the wisdom of God, by which all things are created, which caused not rods, but cattle, to be born from cattle; but that the color of the cattle conceived should be in any degree influenced by the variety of the rods, came to pass through the soul of the pregnant cattle being affected through their eyes from without, and so according to its own measure drawing inwardly within itself the rule of formation, which it received from the innermost power of its own Creator. How great, however, may be the power of the soul in affecting and changing corporeal substance (although certainly it cannot be called the creator of the body, because every cause of changeable and sensible substance, and all its measure and number and weight, by which are brought to pass both its being at all and its being of such and such a nature, arise from the intelligible and unchangeable life, which is above all things, and which reaches even to the most distant and earthly things), is a very copious subject, and one not now necessary. But I thought the act of Jacob about the cattle should be noticed, for this reason, viz. in order that it might be perceived that, if the man who thus placed those rods cannot be called the creator of the colors in the lambs and kids; nor yet even the souls themselves of the mothers, which colored the seeds conceived in the flesh by the image of variegated color, conceived through the eyes of the body, so far as nature permitted it; much less can it be said that the creators of the frogs and serpents were the bad angels, through whom the magicians of Pharaoh then made them.
