Isaiah 40:15

15. The nations are as a drop So far the omnipotence and omniscience of God: now his exaltation as governor of the universe. Necessarily, all expressions of God’s natural attributes are anthropomorphic, after the limited human way of speaking; and, whatever metaphysicians may say, or attempt to say, Isaiah, the greatest of the prophets intellectually, never attempts to get beyond this. The thought here is, that the great nations of earth are no more a burden resting upon the King of the world than a drop hanging from a bucket is a burden to the man carrying it no more than the weight in the balances is perceptibly increased by the smallest sand atom that lies upon it.

Isles Or fragments of the solid continent on which the heathen world is scattered, are to Him who carries the universe like the smallest dust rising in the air. Delitzch.
