28. Verse 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.

It is very common in the Word for 'waters' to mean cognitions and facts, and consequently for 'seas' to mean a gathering together of them, as in Isaiah,

The earth will be full of the knowledge of Jehovah as the waters covering the sea. Isaiah 11:9.

And in the same prophet, with reference to a lack of cognitions and facts,

The waters will dry up from the sea, the river will be parched and dry, and the streams will diminish. Isaiah 19:5-6.

In Haggai, with reference to a new Church,

I will shake the heavens and the earth, and the sea and the dry land; and I will shake all nations, and the desire of all nations will come, and I will fill this house with glory. Haggai 2:6-7.

And with reference to someone who is to be regenerated, in Zechariah,

There will be one day - it is known to Jehovah - not day and not night, for at evening time there will be light; and on that day living waters will flow out from Jerusalem, part of them to the eastern sea, and part of them to the western sea. Zechariah 14:7-8.

In David where the person is described who, having been vastated, is to be regenerated, and to worship the Lord, Jehovah does not despise His bound ones. Heaven and earth will praise Him, the seas and everything that creeps in them! Psalms 69:33-34.

That 'the earth' means that which receives is seen in Zechariah,

Jehovah is He who stretches out the heavens, and founds the earth, and forms the spirit of man within him. Zechariah 12:1.

5820. 'Return, buy us a little food' means that the good of truth should be made their own. This is clear from the meaning of 'buying' as making one's own, dealt with in 5397, 5406, 5410, 5426; and from the meaning of 'food' as the good of truth, dealt with in 5410, 5426, 5487, 5582, 5588, 5655. In general spiritual food includes all good, but specifically it is good acquired by means of truth, that is, truth existing in will and action. For by virtue of being willed and acted out that truth becomes good and is called the good of truth. Unless truth becomes good in this manner it is of no use whatever to a person in the next life; for when he enters that life it goes away from him because it does not fit in with what he wills or consequently with what he loves and takes delight in. In the world a person may have learned the truths of faith not so that he may will them and act them out, and in so doing may make them forms of good, but merely so that he may know and teach them with a view to acquiring position and gain. Even though as a result of this he may be reputed in the world to be very learned, those truths are taken away from him in the next life, and he is left with what he really wills, that is, with the life really his own. What he had been like so far as that life was concerned he continues to be; and, surprising though it may be, he turns away from all the truths of faith and refuses to accept them, no matter how firmly he had embraced them previously. The conversion of truths therefore into forms of good through willing them and acting them out, that is, through living according to them, is what making the good of truth their own implies, meant by 'buy us a little food'.
