Princessij, welcome to Thorn Tree.
There is absolutely no problem at all entering Egypt with an Israel visa in your passport. Egypt and Israel signed a peace treaty decades ago. Hundreds of people, including Israelis, cross from Israel to Egypt every day. You have nothing to worry about.
If you have any more questions you should start a new thread. This one is months old and the only people who are likely to see it are those who have already posted replies on it (which is how I saw it). A new thread will appear at the top of the forum and be seen by more people.
