Commentaries
40:12-17 All created beings shrink to nothing in comparison with the Creator. When the Lord, by his Spirit, made the world, none directed his Spirit, or gave advice what to do, or how to do it. The nations, in comparison of him, are as a drop which remains in the bucket, compared with the vast ocean; or as the small dust in the balance, which does not turn it, compared with all the earth. This magnifies God's love to the world, that, though it is of such small account and value with him, yet, for the redemption of it, he gave his only-begotten Son, Joh 3:16. The services of the church can make no addition to him. Our souls must have perished for ever, if the only Son of the Father had not given himself for us.
12. Lest the Jews should suppose that He who was just before described as a "shepherd" is a mere man, He is now described as God.
Who—Who else but God could do so? Therefore, though the redemption and restoration of His people, foretold here, was a work beyond man's power, they should not doubt its fulfilment since all things are possible to Him who can accurately regulate the proportion of the waters as if He had measured them with His hand (compare Isa 40:15). But Maurer translates: "Who can measure," &c., that is, How immeasurable are the works of God? The former is a better explanation (Job 28:25; Pr 30:4).
span—the space from the end of the thumb to the end of the middle finger extended; God measures the vast heavens as one would measure a small object with his span.
dust of the earth—All the earth is to Him but as a few grains of dust contained in a small measure (literally, "the third part of a larger measure").
hills in a balance—adjusted in their right proportions and places, as exactly as if He had weighed them out.
