Numbers 9:5-7

Living Bible

^4-5 So Moses announced that the Passover celebration would begin on the evening of April first, there in the Sinai peninsula, just as the Lord had commanded. ^6-7 But as it happened, some of the men had just attended a funeral and were ceremonially defiled by having touched the dead, so they couldn’t eat the Passover lamb that night. They came to Moses and Aaron and explained their problem and protested at being forbidden from offering their sacrifice to the Lord at the time he had appointed.
