Isaiah 40:12
12Who has measured the waters in the hollow of his hand, and marked off the sky with his span, and calculated the dust of the earth in a measuring basket, and weighed the mountains in scales, and the hills in a balance?
Who has measured waters in the hollow of a hand, marked heavens with a span, weighed mountains? Wesley: who can do this but God? The discourse of infinite power and wisdom is added to give greater assurance that God was able to do the wonderful things He had promised.
Omnipotence serves the comfort of 40:1–11. The God who measures the sea is not waiting to discover whether He can keep a word. No dispute here: only God does this.
Who hath measured? Calvin: he proclaims power so that the promises may be believed; Abraham did not hesitate because he believed God who promised was able to perform. Restore a people beyond belief requires minds raised above the world, not limited to human means.
Reformed: if this conviction were seated in the heart we would not be so alarmed. Common ground with Wesley: the measuring God can do what He said. Sovereignty here is why the highway and the shepherd are not wishes.
