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).
"To the king, [my] lo[rd, my Sun]: Message of Ili-ra[pih, your servant]; message of Gu(b)la, [your maidservant. I fall at] the feet of the lord, the Sun, 7 times and [7 times]. Do not neglec[t Gu-la, your city and the city of [your] ancesto[rs] from most ancient times. Moreover, behold Gu-la! Just as Hikuptah, so is Gu-la to the king, my lord. Do not neglect the delicts of a serva[nt], for he acted as he pleased in the lands of the king-(i.e. the "king's" brother: Rib-Hadda). Here is the crime that Aziru ... against the king: [he kill]ed the king of Ammiya, and [the king of E]ldata-(Ardata), and the king of Ir(qata)-(="King Aduna"), [and a co]mmissioner of the king, my lord. He also broke into Sumur.
[And indeed] he is now intent on [committing] a cri(me) against the king. Moreover, ... ...May the king (my) lord, know [I] am his loyal servant. And so let him send a garrison to his city—30 to 50 men— as far as Gubla. The king is to take (n)o account of whatever Aziru sends him. Where were the things that he sends coveted? It is property belonging to a royal whom he has killed that he sends to you. Look, Aziru is a reb(el) against the king, my lord."Ili-Rapih Wikipedia

I fall at the feet of my lord, the Sun, 7 times and 7 times. The king, my lord, shall not neglect Gubla, his maidservant, a city of the king from most ancient times. Moreover why did the king communicate through Aziru? He does as he pleases. Aziru killed Aduna, and a magnate. He took their cities. To him belongs Sumur-(Zemar); to him belong the cities of the king. Gubla alone is a ... of the king. Moreover, he broke into Sumur and Ullassa. Moreover, Aziru even [com]mitted a crime [wh]en he was brought [in]to you-(i.e. over-to you, (in Egypt)). The crime [was against] us.
