The Red Sea and the Old Testament Baptisms

There were many baptisms in the old testament. They were ritual washings that the priests had so they could enter into god's presence. The fulfilment of that is now we can literally enter the presence of god through not many levitical baptisms, because now it's open to all people. And this is also clear in, for example, the parallein first corinthians, af paul makes with the account of the red sea. So these are like the two great examples of pre baptismal baptists. There are others as well. We have more than just occasional texts that say, oh, save by baptism without any context. It comes from outside of the text.
