someone who is trained to perform a Jewish circumcision (= the act of cutting the protecting loose skin off a boy's penis), usually in a traditional ceremony

Many Jewish parents hold a bris in the home, where the cutting is done by a trained person called a mohel. 许多犹太父母在家中举行割礼，由受过专门训练的人（也称‘割礼执行者’）来完成割礼。

There were plenty of mohelim in Tel Aviv.
