Arial Hebrew font is gone

Hi! I don't know if this question has been already answered i'm kinda new in apple products.

Here is the problem, i was using M. Word and then when i wanted to change the font to Arial Hebrew it changed to Calibri... very annoying, so i have tried restarting the mac, searched online but nothing, all the other fonts are working as usual, but the one i need it's not.

I will appreciate any help you can provide me.

Thanks!
