Upu
Upu or Apu, also rendered as Aba/Apa/Apina/Ubi/Upi. was the region surrounding Damascus of the 1350 BC Amarna letters. Damascus was named Dimašqu/Dimasqu/ etc.. Etakkama of Qidšu in the Beqaa is in partial control, between allegiance to Pharaoh, and conjoining forces with the king of Hatti.
An example of the intrigue is from the last third of EA 53, :
The intrigue of the three Amarna letters appears to involve areas to the north and northwest of Damascus, into Lebanon and the Beqaa.
And, for example Tašša, appears to be "Tahash," Tahaš, named after the biblical 'Tahash' personage; see: Patriarchs.
