The following explains the above passage, Then look at the face of the heavens, etc., which in turn is an explanation of the verse quoted.
Firstly, the phrase: How it is silent in its tranquillity.
The verse directs an attentive gaze to the beautifully adorned face of the heavens so that the one beholding it may become aware of the silence there which is within a vast tranquillity. And so that he may understand that it is thus through the command and subjugation of One Possessing Absolute Power.
For if they had been independent and unrestrained, those huge globes, all in close proximity to each other, those infinite, awesome heavenly bodies, would have caused such an uproar with their enormously swift revolutions that they would have deafened the cosmos. And there would have been such confusion in that tumultuous commotion that it would have scattered the universe. It is well-known what a commotion and uproar it causes if twenty water-buffalo work on top of each other. Whereas, we know that there are among the stars some which are thousands of times larger than the earth and which revolve at a speed seventy times faster than that of a cannon-ball. So the degree of power and subjugation of the Glorious Maker and All-Powerful One of Perfection may be understood from this, together with the degree of obedience and submission to Him of the stars.
Secondly, the phrase: How it is in motion with wisdom.
The verse commands us to look at the motion on the face of the heavens, which is with wisdom and purpose. Indeed, that mighty, wondrous motion occurs within a precise and comprehensive wisdom.
For example, a craftsman who operates a factory's machinery with wisdom and purpose demonstrates the degree of his skill and craftsmanship in proportion to the degree of the order and grandeur of the factory. And so too, when we look at it this way, do the degree of power and wisdom of the All-Powerful One of Glory become apparent to us. For He makes the mighty sun like a factory, and its planets, those awesome, immense globes, like the factory's machinery, which He spins and revolves like stones in a sling.
Thirdly, How it is radiant with majesty, how it smiles with its adornment.
It has this meaning: the radiant majesty and smiling adornment on the face of the heavens are such that they demonstrate just how sublime is the Glorious Maker's sovereignty and how exquisite His artistry. As the myriad electric lamps hung about on festival days demonstrate the degree of the king's majesty and perfection in material progress, the vast heavens, too, with their majestic and adorned stars demonstrate to attentive gazes the sublime sovereignty and exquisite artistry of the Glorious Maker.
Fourthly, By the order in its creation, by the symmetry in its art.
This phrase says the following: look at the order of the creatures on the face of the heavens and see their symmetry and precise balance, then understand just how Powerful and Wise is their Maker.
