Explaining the first clause of Job 38:13, as Job 38:15 does the second clause. As the plastic clay presents the various figures impressed on it by a seal, so the earth, which in the dark was void of all form, when illuminated by the dayspring, presents a variety of forms, hills, valleys, etc.
turned - (Hebrew, “turns itself”) alludes to the rolling cylinder seal, such as is found in Babylon, which leaves its impressions on the clay, as it is turned about; so the morning light rolling on over the earth.
they stand - The forms of beauty, unfolded by the dawn, stand forth as a garment, in which the earth is clad.
