I first came across this word in Matthew Arnold's Culture and Anarchy. He is not writing about culture so much as he is about personal development. He believes that there are many aspects of the self that need development, and herbraise is something that can halt development .
Hebraise is defined as the tendency for humans to get hooked on religion, and focus on this aspect of self-development at the expense of others.
Hebraise is, in other contexts, sometimes an alternate spelling hebraize. Hebraize means 'to take on Hebrew characteristics' (not really a word we use very often); it may be that Matthew Arnold had some antisemitic leanings.
