9 Who is the father of the rain? And who has begotten the drops of dew ? Who condensed the air into clouds, and bade them carry the waters of the rain, now bringing golden-tinted clouds from the north, now changing these into one uniform appearance, and again transforming them into manifold circles and other shapes? Who can number the clouds in wisdom? Whereof in Job it says, And He knows the separations of the clouds, and has bent down the heaven to the earth: and, He who numbers the clouds in wisdom: and, the cloud is not rent under Him. For so many measures of waters lie upon the clouds, yet they are not rent: but come down with all good order upon the earth.
Who brings the winds out of their treasuries? And who, as we said before, is he that has begotten the drops of dew? And out of whose womb comes the ice? For its substance is like water, and its strength like stone. And at one time the water becomes snow like wool, at another it ministers to Him who scatters the mist like ashes, and at another it is changed into a stony substance; since He governs the waters as He will. Its nature is uniform, and its action manifold in force. Water becomes in vines wine that makes glad the heart of man: and in olives oil that makes man's face to shine: and is transformed also into bread that strengthens man's heart, and into fruits of all kinds which He has created.
