How do you say "raca"?

Excuse me, could you clarify for me how one would properly pronounce the word "raca"? I'm not entirely familiar with its pronunciation and would like to ensure that I'm using it correctly in conversation. Is it pronounced with a long "a" sound, like in the word "race," or is it more like the short "a" in "cat"? Or perhaps there's another pronunciation entirely? I'd appreciate your guidance on this matter.
