Seriously. I just thought maybe it could have been a translation error. I haven't been through my Quran completely so I have no idea. Buddism is confusing enough... I never did completely understand it either.
And, didn't Arabic's keep the Hebrew's as slaves, or was that the Persians?
Babylon, Persia, some other folk. It was a popular pastime in the Middle East, "Let's go conquer and enslave the Hebrews."
One thing to remember is that "Semitic" is a language family, not a racial group. Members of the family include Hebrew, Arabic, Akkadian, Phoenician, Assyrian, and many others, most of them now extinct as languages.
The Arabic people are actually rather a latecomer to the region. The Arabian peninsula wasn't really settled until the late second early first millennium BC (largely coinciding with the domestication of the camel) giving the Hebrews a few hundred years "lead" on them with their arrival in Canaan (historical sources are kind of sketchy making details hard to pin down).
