i think hebrew is fairly phonologically simple, isn't it
on glancing at the overview, the only thing that looks remotely challenging is that [χ] (כ or ח) contrasts with [ʁ] (ר)
even the vowel system is roughly the same five-vowel system used by languages like spanish (and nearly japanese), and both consonantal gemination and phonemic vowel length have been dropped in modern hebrew
we're not talking about something like keresan here
so what are you on about
