Jewish circumcision refers to the removal of the loose, roll-like skin covering the sensitive genitals of a man.
Circumcision is a popular traditional religious ceremony among the Jews. In Hebrew, this ceremony is called "covenant" or "covenant of circumcision." Mohan was the executor of circumcision. If the baby boy has no reasons for delay such as illness or other health problems, Mohan will perform circumcision on the eighth day after birth. During the circumcision, Mohan will give a blessing and declare that the baby boy has fulfilled the law. Then the baby boy's parents will give a blessing to show that their son has been included in the contract between God and the Jews, and officially name the baby boy.
According to the records in Genesis 17:9-14 of the Bible, God commanded Abram to be circumcised for himself, his male descendants, and his servants as a permanent contract. According to Halakah, the oral law of medieval Judaism, those who did not follow circumcision would be regarded as intentional sins and would incur the punishment of being cut off from God. For Jews, circumcision of a male child on the eighth day after birth has special sacred significance.
Jewish religious beliefs
The main religious belief of Jews today is Judaism, but a small number of people have converted to other religions, such as Christianity, and many Jews are atheists. But Jewish traditions will still be preserved. Most of these Jews live in other countries outside Israel (Jews who have converted to Christianity are not recognized as Jews in Israel).
Judaism worships the single main god Yahweh (called Jehovah in Christianity) and is the national religion of the Hebrews. Judaism considers the Talmud to be second only to the Bible, and Judaism has given rise to the two largest religions in the world - Christianity and Islam.
There are very few people who believe in Judaism in the world, and they are only limited to the Jews. There are not as many people who believe in Sikhism and Shintoism, but every book that introduces religion must mention Judaism. Mainly because of its huge impact.
