| Geneva Study Bible And God made the firmament, and divided the waters which were {f} under the firmament from the waters which were above the firmament: and it was so. (f) As the sea and rivers, from those waters that are in the clouds, which are upheld by God's power, least they should overwhelm the world. Wesley's Notes 1:6-8 We have here an account of the second day's work, the creation of the firmament. In which observe,
1. The command of God; Let there be a firmament - An expansion; so the Hebrew word signifies, like a sheet spread, or a curtain drawn out. This includes all that is visible above the earth, between it and the third heavens, the air, its higher, middle, and lower region, the celestial globe, and all the orbs of light above; it reaches as high as the place where the stars are fixed, for that is called here the firmament of heaven, Ge 1:14,15, and as low as the place where the birds fly for that also is called the firmament of heaven, Ge 1:20.
2. The creation of it: and God made the firmament.
3. The design of it; to divide the waters from the waters - That is, to distinguish between the waters that are wrapt up in the clouds, and those that cover the sea; the waters in the air, and those in the earth.
4. The naming it; He called the firmament Heaven - 'Tis the visible heaven, the pavement of the holy city. The height of the heavens should mind us of God's supremacy, and the infinite distance that is between us and him; the brightness of the heavens, and their purity, should mind us of his majesty, and perfect holiness; the vastness of the heavens, and their encompassing the earth, and influence upon it, should mind us of his immensity and universal providence. Matthew Henry's Concise Commentary 1:6-13 The earth was emptiness, but by a word spoken, it became full of God's riches, and his they are still. Though the use of them is allowed to man, they are from God, and to his service and honour they must be used. The earth, at his command, brings forth grass, herbs, and fruits. God must have the glory of all the benefit we receive from the produce of the earth. If we have, through grace, an interest in Him who is the Fountain, we may rejoice in him when the streams of temporal mercies are dried up. |
