It is possible that you failed to understand what was said. As I can show you three different waters and three different colours, and I can also show you three different animals to verify the facts.
Look here the Bible mentions three heights of waters as in the sea, the river, and the stream:
"And the Lord shall utterly destroy the tongue of the Egyptian sea; and with his mighty wind shall he shake his hand over the river, and shall smite it in the seven streams, and make men go over dryshod".
Just as here the Bible mentions three animals as in the cattle, the goats, and the sheep:
"And as for you, O my flock, thus saith the Lord God; Behold, I judge between cattle and cattle, between the rams and the he goats".
Just as here the Bible mentions three colours as in the red, the purple, and the blue:
"And of the blue, and purple, and scarlet, they made cloths of service, to do service in the holy place, and made the holy garments for Aaron; as the Lord commanded Moses".
Now try to understand here the speech is overlapping:
The Red Sea:
"To him which divided the Red sea into parts: for his mercy endureth for ever"
So can you notice the Red Sea is as an overlap of the three waters and the three colours?
Look:
Red - Purple - Blue
Sea - River - Steam
Cattle - Goat - Sheep
And for verification the Red Heifer can be seen as another overlap. An overlap of the three animals and the three colours.
The Red Heifer (Cattle):
"This is the ordinance of the law which the Lord hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke".
Are you able to understand this concept of what is said? Can you now clearly hear the words "Red Sea" differently? Do you require further verification of the fact of the Red Sea overlap? I can show it.
