Isa 40:12
In order to bring His people to the full consciousness of the exaltation of Jehovah, the prophet asks in Isa 40:12, “Who hath measured the waters with the hollow of his hand, and regulated the heavens with a span, and taken up the dust of the earth in a third measure, and weighed the mountains with a steelyard, and hills with balances?” Jehovah, and He alone, has given to all these their proper quantities, their determinate form, and their proportionate place in the universe. How very little can a man hold in the hollow of his hand (shō‛al)! how very small is the space which a man’s span will cover! how little is contained in the third of an ephah (shâlı̄sh; see at Psa 80:6)! and how trifling in either bulk or measure is the quantity you can weight in scales, whether it be a peles, i.e., a steelyard (statera), or mō'zenayim, a tradesman’s balance (bilances), consisting of two scales.
But what Jehovah measures with the hollow of His hand, and with His span, is nothing less than the waters beneath and the heavens above. He carries a scoop, in which there is room for all the dust of which the earth consists, and a scale on which He has weighed the great colossal mountains.
