When is Passover celebrated compared with Yom Kippur?
Passover is celebrated in the Spring of the year, associated with the Spring Equinox, while Yom Kippur, or Atonement, is in the Fall of the year. They are two totally different Feast Days; Passover involved the blood of the lamb and protection from the death angel.
Les explains that Passover and Atonement are two totally different Feast Days. Passover was in the Spring, associated with the Spring Equinox, and is still celebrated by the Jews today in the Spring of the year. Atonement, or Yom Kippur as they call it today, is in the Fall of the Year. In the context described, the death angel would pass over every house in Egypt, but Israel had an out: by faith they put the blood of the Passover lamb on the doorposts and stayed within the safety of their home, so the death angel would pass over. Les notes that Christ is our Passover, and he plans in another program to cover the period from 12 noon till 3 in the afternoon as an analogy of His work of Atonement, but here the focus is the Passover aspect—protection given by the blood of the Lamb.
