Exodus 12:15

The seven days beginning with the Passover are to be kept as a feast of unleavened bread. The Passover (pesach) and feast of Unleavened Bread (mazzoth) are really distinct, but as they were always celebrated in succession the name Passover is sometimes used to cover both: cp. Luke 22:1. Shall be cut off] This does not necessarily mean put to death, but excommunicated and cast out of the congregation of Israel. A person so cut off becomes like one of a heathen nation. He is reduced to the level of an uncircumcised person, being outside the covenant and having no more part in the privileges of the chosen people: see on Genesis 17:14,; and cp. Matthew 18:17; Ephesians 2:12.
