Humphrey had become lord of Toron sometime before 1140 when he married the daughter of Renier Brus, lord of Banias (the Herodian city of Caesarea Philippi). Through this marriage, Banias was added to Toron. Humphrey became castellan of Hebron in 1149 when Hebron became a domain of the royal family of Jerusalem. In 1153 he became constable of Jerusalem when Baldwin III of Jerusalem became sole ruler after a struggle with his mother Melisende. That year he was present with the king at the Siege of Ascalon.
