19. OLD COVENANT: The Day of Atonement to be an everlasting annual statute
This is described in Leviticus 16: 34, “This shall be an everlasting statute for you, to make atonement for the children of Israel, for all their sins, once a year.”
19. NEW COVENANT: The New Covenant replaced the Old Covenant
Because of the constant rebellion of the Children of Israel God replaced the Old Covenant with a New Covenant. Jesus Christ fulfilled the Old Covenant by becoming the sacrificial Lamb of God himself.
The Bible records in Hebrews 7:27, “:He (Jesus Christ) died once for all when He offered up Himself”.
The Crucifixion occurred once in history, as an everlasting New Covenant between God and man.
