And this, again, was due to what is commonly called the law of gravitation, or of the attraction of matter. Light is not itself a substance, but is a condition or state of matter and this primæval light was probably electric, arising from the condensation and friction of the elements as they began to arrange themselves in order. Let there be light: and there was light.-The sublimity of the original is lost in our language by the cumbrous multiplication of particles. We have, then, here nature’s first universal law. His commands are not temporary, but eternal and whatever secondary causes were called into existence when the Elohim, by a word, created light, those same causes produce it now, and will produce it until God recalls His word. God, then, by speaking, gives to nature a universal and enduring law. The Supreme One speaks: with the rest, of hear is to obey. So in the cognate languages the word Emir, ruler, is literally, speaker. His word alone contains all things necessary for the fulfilment of His will. The beauty and sublimity of the language here used has often been noticed: God makes no preparation, He employs no means, needs no secondary agency.

The phrase, then, is metaphorical, and means that God enacted for the universe a law and ten times we find the command similarly given.

(3) And God said.-Voice and sound there could be none, nor was there any person to whom God addressed this word of power. Ellicott's Commentary for English ReadersTHE CREATIVE DAYS.
