Mine hand also hath laid the foundation of the earth,.... Which is ascribed to the Wisdom, Word, and Son of God, Pr 3:19. This Aben Ezra and Kimchi interpret of the left hand , seeing the work of the heavens is ascribed to the right hand in the following clause; the earth being less honourable than the heavens:and my right hand hath spanned the heavens; stretched them out as a curtain or canopy over the earth, and measured them out with a span, as easily as a man measures anything with his hand; see Isa 40:12,when I call unto them, they stand up together; or, "I called them, and they stood up together", as the Targum; and so may refer to the first creation of them, when at the word of God, and by his almighty fiat, they rose into being at once, Ps 33:9.
Kimchi observes, that the houses of Hillell and Shaminai were divided about this matter, which were created first, the heavens or the earth; at which R. Simeon ben Jochai wondered, since, according to the text, they were both created together ; though this may be understood of the consistence and permanency of the heavens and the earth, being upheld by the Lord, and by the word of his power, and of the ready obedience of the heavenly bodies to do his will, who, like servants, rise up at once at the word of his command; see Isa 40:26.
