If you are doing more than a couple words now and then in Hebrew, then consider using
Mellel. The Hebrew support is great including directional changes (not just a word, but sentences and paragraphs, which you can change on the fly), etc. There are many fonts available that work, my favorite
Ezra from SIL,
SBL Hebrew, and check out the Mellel forums for those who write in Hebrew every day,
