2 Kings 20:10 - Exposition

And Hezekiah answered, It is a light thing for the shadow to go down ten degrees. Hezekiah views it as a comparatively easy thing for the shadow, which is already descending the steps, to accelerate its pace and rapidly descend fifteen degrees instead of slowly traversing them; and therefore accepts Isaiah's other offer. Nay, but let the shadow return backward ten degrees. Let it, i.e; change its direction, and having descended a certain distance, suddenly return and ascend again. This will be no "light thing," but a great marvel, which will thoroughly convince him. The thought was natural, though perhaps not strictly logical.
