Tweety, that is good thinking, or rather receiving revelation.
I had never seen this as being Jesus until I was writting a message, think it was on one of the days in Genesis. (dont know for sure). But as I was writting it, God gave me the revelation of this being about Jesus.
I had always seen it as being when he sent the flood. And I know that is one side of the revelation. But as you show, there are two sides or more, to this.
But this is the Scripture which leads me to believe that the people did not leave Eden until that flood.
Lebanon in Scripture stands for Eden. It shows that Garden.
those trees were the different nations of people who lived in that Garden, before the flood.
