Which Aramaic? Modern Syriac or Aramaic from the time of the Bible?
Syriac:
ܒܪܐܩ ܚܘܣܝܢ ܐܘܒܐܡܐ
I guess the Biblical version would be:
בראק חוסין אובאמא
That’s simply converting the Syriac to Hebrew letters. As a Hebrew speaker, if I were to guess how it would supposed to be written in Biblical Aramaic I would simply write:
ברק חוסין אובמא
As a side note, the modern Hebrew is:
ברק חוסיין אובמה
