This informative article by the late Rabbi Louis Jacobs explains the origins, meaning, and practice of the Priestly Blessing in the synagogue service, which also is part of the blessing over the children on Friday nights. The author describes when, where and how the ritual is practiced, as well as introducing the concept of the Kohanim (Priests) as Divine conduits. This article, reprinted on MyJewishLearning.com, is an excerpt from Rabbi Jacob's book "The Jewish Religion: A Companion," a comprehensive work on Jewish belief and practice, wisdom and culture, history and tradition. Rabbi Louis Jacobs was the first leader of Masorti (Conservative) Judaism in the United Kingdom.
