The Book of Jubilees, part of the Ethiopian Orthodox biblical canon, written in the time of John Hyrcanus, reveals the hostility directed against those who abandoned circumcision (xv. 26–27): "Whosoever is uncircumcised belongs to 'the sons of Belial,' to 'the children of doom and eternal perdition'; for all the angels of the Presence and of the Glorification have been so from the day of their creation, and God's anger will be kindled against the children of the covenant if they make the members of their body appear like those of the Gentiles, and they will be expelled and exterminated from the earth".
