Arcana Coelestia #564
564. Verse 1. And it came to pass that man began to multiply himself upon the faces of the ground, and daughters were born unto them. By “man” [homo] is here signified the race of mankind existing at that time. By the “faces of the ground” is signified all that tract where the church was. By “daughters” are here signified the things appertaining to the will of that man, consequently cupidities.
Genesis 6:19
19
Of every living thing of all flesh, you shall bring two of every sort into the ship, to keep them alive with you. They shall be male and female.
