In order for water to separate in fulfillment it would have to come back together...again (lol). It's like the prophecy in Isaiah 7:14 of the virgin birth. We all attribute this prophecy to Christ (as we should), but that prophecy was first fulfilled centuries before in the time of Israel with the birth of the child name Maher-Shalal-Hash-Baz. So it happened at that moment in time, but then was fulfilled again later.
We can even use Adam as an example. Adam entered into a deep sleep, his side was opened, and out came the material to form his wife Eve (whose Hebrew name is "chavah" meaning "life"). Thousands of years later, the 2nd Adam (Christ) entered the sleep of death, his side was pierced open by the spear, and out came blood and water (both symbols of "life"). It is then by this blood that the bride of Christ is formed.
Ecclesiastes 1:9
"What has been is what will be. What has been done is what will be done. There is nothing new under the sun."
Isaiah 46:9-10
9 Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,
10 Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
So the question arises, when did Yah declare the end? He had to declare it at some point in the books prior to saying this in Isaiah 46. And what is the end of all things? Well the end is described in Revelation 22 with the
tree of life and Eden restored. Now if we dig deeper past the translation, the last line starts by saying "Declaring the end from
Bereshit...", which just so happens to be the same name of the first book of scripture, which just so happens to be when Eden and the tree of life was first created.
So the end was literally declared from Genesis when Yah created his kingdom during creation week.

Yes! Joseph does have that specific dream about them bowing down to him...but Yah didn't declare anything in the dream to or about mankind. What I mean is, he wasn't talking to anyone in that instance about mankind's drama worldwide like he did with:
Adam (mankind cursed)
Noah (mankind destroyed by water)
Abraham (mankind blessed by seed)
Christ (mankind healed by Sun)
John the servant of Revelation (mankind's final drama; restoring the garden)
I'm not saying Joseph's dream wasn't prophetic as there are a multitude of prophecies in scripture. I'm just saying it may not have been for mankind you know?
Hmm. That's interesting. I'm curious as to why you'd pick the date 2028? May I ask where these specific years came from?
As far as when the seventh day begins; it's whenever Christ appears I guess...but we know how much time has past to know where we are in this grand drama of ours. I'm reminded of how Moses asked to see Yah. Yah said no one can see his face but He'll show Moses his back as he passes by. So we're allowed to see what has passes in Yah's plan.
