Emebert was possibly a missionary bishop who evangelized Brabant, his native country.[5] After the death of his sister Gudula in 712, her tomb was desecrated, and Emebert then excommunicated the desecrators.[6]
According to the Gesta Episcoporum Cameracensis (Acts of the Bishops of Cambrai), he was buried in a place called Ham, located in the vicinity of Cambrai. His body was afterwards taken to Maubeuge Abbey,[7] where his mother had become a nun. He is probably identical with Bishop Hildebert of Cambrai-Arras, who died around 700 and is buried at Maubeuge.[8]
His feast day is celebrated on the 15 January.[9] He is particularly venerated at Arras, Cambrai and Ghent. He is also venerated in the Orthodox Church on February 22.[10]
