創世記 1:10 註釋：Rashi, Ibn Ezra, Ramban & Rashbam

קרא ימים CALLED HE SEAS — But does it not form one great sea? But it speaks of seas because the taste of fish which comes up from the sea at Acco is not the same as the taste of fish which comes up from the sea at Aspamia (Genesis Rabbah 5:8).

It said "seas" - since there is not [single] sea which encompasses the entire landmass.

AND G-D CALLED THE DRY LAND EARTH. The verse states that the proper name for it would be yabashah (dry land) for as the waters are separated from the sand it becomes dry. However, He called it eretz (earth) as the name which included the four elements created on the first day. The reason for this is that they were all created for the sake of the earth in order that there be a habitation for man, since among the lower creatures no one but man recognizes his Creator.¹²⁹This is a major principle in Ramban’s thought, that the purpose of all existence is that man acknowledge his Creator. “We have no other reason for the Creation.” (See end of Seder Bo in the Book of Exodus).
And the gathering together of the waters He called ‘yamim’ (seas). It is as if [the word yamim, (seas) combines the two words] yam and mayim (a sea of waters), for the bottom of the ocean is called yam, as it is written, As the waters cover the sea,¹³⁰Isaiah 11:9. and likewise, And he took down the sea from off the brazen oxen.¹³¹II Kings 16:17. It is called “sea” because there was a large gathering of water in it.
