Go forth and multiply

Biblical it is:

Noah's flood----Genesis 6 to 8

And so it was to be, that after the waters receded, Noah commanded all
the animals to "Go forth and multiply."

Wow, quick response - thank you.

The ark quickly emptied, except for two small snakes, who stayed behind.
When Noah asked them why, they replied, "We can't multiply. We're
adders."

Noah, being the resourceful man he was, immediately got busy cutting
down trees and building a large table with the unfinished lumber
therefrom.

And he saw that it was good.

The snakes were overjoyed when Noah picked them up and placed them on
it. Noah and the snakes both knew that even adders could multiply on
a log table.

Ha ha! You are a wordsmith of the highest order (purple belt). I bow to your superior plagarism ;-)

Here in London SW1 it has a more profane meaning. To tell someone to 'Go forth and multiply' is to tell them, in a polite way, to '[F-word] off'. It may be considered rude but, there you go, it's widely used hereabouts so I thought you ought to be fully informed.
