43. Verse 22 And God blessed them, saying, Be fruitful and multiply, and fill the waters in the seas; and let birds be multiplied upon the earth.

Everything that has life in it from the Lord is fruitful and multiplies without limit. This does not happen during a person's lifetime, but in the next life it does so to an astonishing extent. In the Word 'to be fruitful' has reference to matters of love, while 'to multiply' has reference to matters of faith. The fruit of love contains the seed by which it multiplies itself to so great an extent. The Lord' s blessing also means, in the Word, fruitfulness and multiplication, for they are the outcome of that blessing.

Verse 23 And there was evening, and there was morning, a fifth day.

5582. 'Turn back, buy a little food for us' means that, so as to have life, they should acquire the good of spiritual truth. This is clear from the meaning of 'buying' as acquiring and making one's own, dealt with in 4397, 5374, 5397, 5406, 5410, 5426; and from the meaning of 'food' as the good of truth, dealt with in 5340, 5342. Here the good of spiritual truth is meant, because this kind of good is the subject in what follows. That the purpose was for them to have life follows from this.
