Charles H. Spurgeon on Psalms 115:16

The heaven, even the heavens, are the LORD'S. He demonstrates, that, as God has his dwelling place in the heavens, he must be independent of all worldly riches; for, assuredly, neither wine, nor corn, nor anything requisite for the support of the present life, is produced there. Consequently, God has every resource in himself. To this circumstance the repetition of the term "heavens" refers. The heavens, the heavens are enough for God;and as he is superior to all aid, he is to himself instead of a hundred more. John Calvin.
