Yes Jews practice circumcision too as does certain Christian sects as well. I know cos my cousin and her partner, who are Christians believes circumcision to be a part of their faith and will be getting both their boys circumcised soon.
However the reason Jews, Christians, and Muslims practice circumcision as a religious ritual is due to it being commanded upon us by God originally via the Prophet Abraham, who all three faiths believe in, as did those tribes you mentioned.
