Leupold Genesis part 40 verse 10

10. And God called the dry land earth and the collection of waters He called seas; and God saw that it was good.

The meaning of the word "earth" was discussed under v. 1. The propriety of the use of the term "sea" Was treated just before this verse. What God's calling signifies was shown in connection with v. 5.

Here is the place for discussing what reasonable explanation may be offered for the fact that at the conclusion of the work of the second day the customary approval of the Creator is not recorded (v. 8); but that it does appear now at the conclusion of the work of the third day (v. 10). As was shown at the beginning of the explanation of v. 9, the work of the second day reaches back and completes the work of' the first day from one point of view. In a more decided sense the work of the third day reaches back and completes the work of the second in reference to the separation of water. The second day merely raises the surface fogs making them clouds, but the earth waters are still entangled with the solid matter. So the work of the second day was relatively incomplete, so much so that the divine approval, "it was good," was withheld, but it is in reality included in the approval bestowed upon the third day.

Note the chiasmus of v. 10: verb, object--object verb (K. S. 339 o).
