The most obvious Persian loanwords in pre-70 ᴄᴇ Hebrew and Aramaic are the following...
rabmag: 'high priest.' The compound noun is from Hebrew rab 'great' and Persian mag...
qinamon: 'cinnamon'.

Firstly, in Jeremiah 39 rab mag appears as two words - רב מג - rather than one - רבמג. Secondly, commentators tend to associate רב מג in Jeremiah 39 with Akkadian rab mugi rather than giving it a Persian etymology.
As for qinamon, the origin of this word is debated and it therefore not appropriate in a list of "obvious Persian loanwords."

ָAll forms of Jewish mysticism, from about 300 ʙᴄᴇ to the pre-Medieval Sefer haRazim until today, were developed because of this word, raz (ספר הרזים), and the reflections it generated.

This is absurd. Mysticism develops because seekers wish to connect with the transcendent order, not because a Persian word catches their fancy.
