God gave them. - The absolute giving of the heavenly bodies in their places was performed at the time of their actual creation. The relative giving here spoken of is what would appear to an earthly spectator, when the intervening veil of clouds would be dissolved by the divine agency, and the celestial luminaries would stand forth in all their dazzling splendor.

And God set them in the firmament of the heaven,.... He not only ordered that there they should be, and made them that there they might be, but he placed them there with his own hands; and they are placed, particularly the sun, at such a particular distance as to be beneficial and not hurtful: had it been set nearer to the earth, its heat would have been intolerable; and had it been further off it would have been of no use; in the one case we should have been scorched with its heat, and in the other been frozen up for the want of it. The various expressions used seem to be designed on purpose to guard against and expose the vanity of the worship of the sun and moon; which being visible, and of such great influence and usefulness to the earth, were the first the Heathens paid adoration to, and was as early as the times of Job, Job 31:26 and yet these were but creatures made by God, his servants and agents under him, and therefore to worship them was to serve the creature besides the Creator,

To give light upon the earth; this is repeated from Genesis 1:15 to show the end for which they were made, and set up, and the use they were to be of to the earth; being hung up like so many lamps or chandeliers, to contain and send forth light unto the earth, to the inhabitants of it, that they may see to walk and work by, and do all the business of life, as well as be warmed and comforted thereby, and the earth made fertile to bring forth its precious fruits for the use of creatures in it: and it is marvellous that such light should be emitted from the sun, when it is at such a vast distance from the earth, and should reach it in so short a space. A modern astronomer (m) observes, that a bullet discharged from a cannon would be near twenty five years, before it could finish its journey from the sun to the earth: and yet the rays of light reach the earth in seven minutes and a half, and are said to pass ten millions of miles in a minute.

And God set them in the firmament of the heaven to give light upon the earth,

1:14-19 This is the history of the fourth day's work, the creating the sun, moon and stars. Of this we have an account, In general, verse 14, 15. where we have, The command given concerning them. Let there be lights in the firmament of heaven - God had said, Ge 1:3 Let there be light, and there was light; but that was, as it were, a chaos of light, scattered and confused; now it was collected and made into several luminaries, and so rendered both more glorious and more serviceable. The use they were intended to be of to this earth. They must be for the distinction of times, of day and night, summer and winter. They must be for the direction of actions: they are for signs of the change of weather, that the husbandman may order his affairs with discretion. They do also give light upon the earth - That we may walk John 11:9 and work John 9:4 according as the duty of every day requires. The lights of heaven do not shine for themselves, nor for the world of spirits above, they need them not; but they shine for us, and for our pleasure and advantage. Lord, what is man that he should be thus regarded, Ps 8:3,4. In particular, Ge 1:16,17,18, The lights of heaven are the sun, moon and stars, and these all are the work of God's hands. The sun is the greatest light of all, and the most glorious and useful of all the lamps of heaven; a noble instance of the Creator's wisdom, power and goodness, and an invaluable blessing to the creatures of this lower world. The moon is a lesser light, and yet is here reckoned one of the greater lights, because, though in regard of its magnitude, it is inferior to many of the stars, yet in respect of its usefulness to the earth, it is more excellent than they. He made the stars also - Which are here spoken of only in general; for the scriptures were written not to gratify our curiosity, but to lead us to God. Now, these lights are said to rule, Ge 1:16,18; not that they have a supreme dominion as God has, but they are rulers under him. Here the lesser light, the moon, is said to rule the night; but Ps 136:9 the stars are mentioned as sharers in that government, the moon and stars to rule by night. No more is meant, but that they give light, Jer 31:35. The best and most honourable way of ruling is, by giving light, and doing good.

Margin heaven

i.e. the "heaven" of the stars; e.g. Gen 15:5 Lk 23:43.

1:14-19 In the fourth day's work, the creation of the sun, moon, and stars is accounted for. All these are the works of God. The stars are spoken of as they appear to our eyes, without telling their number, nature, place, size, or motions; for the Scriptures were written, not to gratify curiosity, or make us astronomers, but to lead us to God, and make us saints. The lights of heaven are made to serve him; they do it faithfully, and shine in their season without fail. We are set as lights in this world to serve God; but do we in like manner answer the end of our creation? We do not: our light does not shine before God, as his lights shine before us. We burn our Master's candles, but do not mind our Master's work.
