What is "ili-rapih"

Ili-Rapih was the follow-on mayor in Gubla-(modern Byblos), and the brother of Rib-Hadda, the former mayor of Gubla, (who was the prolific author of letters to pharaoh); Ili-Rapih is in the 1350-1335 BC Amarna letters correspondence, and wrote 2 follow-on letters to the Pharaoh after the death of Rib-Haddi.

Of note, Ili-Rapih's name is referenced in only one letter in the entire Amarna letters corpus, besides his own 2 authored letters of EA 139, and 140, ( EA is for 'el Amarna'), that being letter EA 128, (Rib-Haddi letter no. 57 of 68).
