Hebrew wasn't a spoken language for around 1300 years until a russian zionist rebuilt it from the ground up. Written Hebrew doesn't have vowels, they are just inferred but because nobody spoke it for so long the orriginal vowels are is lost to time.

Before Ben-Yehuda decided what the "official" pronunciations were every different Jewish community had a different idea on how Hebrew should sound influenced by the language of the land they lived in. He mostly used the vowel sounds that other Slavic Jews used and then he made up a bunch of new words that all have that same Slavic version of Hebrew sound to them.
The grammatical structure of modern Hebrew is Verb-Subject-Object (VSO) but in modern Hebrew (as well as Russian) it is Subject-Verb-Object (SVO). There are also many words in modern Hebrew directly taken from Russian which have no other word.
My original point was hyperbole. Obviously Hebrew isn't actually a Slavic language any more than Tolkien's elvish is but it is isn't Semitic either. They are both just made up.
My point was that modern Hebrew has more in common with Slavic languages than with Semitic ones.
