6 Then God said, "Let there be a firmament in the midst of the waters, and let it divide the waters from the waters." 7 Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so. 8 And God called the firmament Heaven. So the evening and the morning were the second day.
9 Then God said, "Let the waters under the heavens be gathered together into one place, and let the dry land appear"; and it was so. 10 And God called the dry land Earth, and the gathering together of the waters He called Seas. And God saw that it was good.

Commentary on Genesis 1:6-13
(Read Genesis 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.
