Raynald came to Jerusalem with Joscelin before 1September 1176 where he became a close ally of Joscelin's sister, Agnes of Courtenay. She was the mother of the young Baldwin IV of Jerusalem, who suffered from leprosy. Hugo Etherianis, who lived in Constantinople after around 1165, mentioned in the preface of his "About the Procession of the Holy Spirit" that he had asked "Prince Raynald" to deliver a copy of the work to Aimery of Limoges. According to historian Bernard Hamilton, these words suggest that Raynald led the embassy that BaldwinIV sent to Constantinople to confirm an alliance between Jerusalem and the Byzantine Empire against Egypt.
