As far as I know, no version of QB supports Hebrew. (See PS below.)

There may have been several foreign language editions of QB, but that would be mostly the Help file. I don't know if they support fonts other than the usual ASCII characters. There were probably several versions in Latin alphabets, but I doubt that a Hebrew version existed. Also remember that QB is 20 years old, and it came out long before a lot of modern improvements.

In order to display foreign language fonts on your computer, you need to use the equivalent foreign language version of the operating system, but I don't know if QBasic (or QBX) can even accommodate that. In the .NET programming languages, the font display is referred to as the "culture."

I tried doing a Google search for QBasic + Hebrew. I came up with something, but it's an old post and the url no longer works. However, you might try the email and see if it's still active. Maybe that person can help you. Otherwise, do your own search. Good luck.

Here is a copy of the reference:

PS: Other than that, you can take Artelius' advice and copy your program to QB64. From there you can figure out how to use UNICODE to display the Hebrew characters. UNICODE is a lot more recent than the last version of QB, which could only use ASCII.
