Laws of Worship of God

The priestly service consisted of ritual worship carried out by priests in the Tabernacle (Mishkan) and later in the Temple. The service included offering daily sacrifices, cleaning and preparing the altar for sacrifice, arranging the menorah for lighting, offering the ketoret, and more. Particulars of the service are discussed in detail in the book of Leviticus and in the fifth order of the Mishnah and Talmud, Kodashim.
