At midnight the Lord killed every firstborn male in the land of Egypt, from the firstborn of Pharaoh, who sat on his throne, to the firstborn of the prisoner in the jail, and also all the firstborn of the livestock.
No one is allowed to dedicate the firstborn of the livestock, because the firstborn belongs to the Lord. Whether they are cattle, sheep, or goats, they are the Lord's.
because all the firstborn are mine. When I killed every firstborn in Egypt I set apart as holy to me all the firstborn of Israel, human and animal. They are mine. I am the Lord.”
How much worse do you think someone will deserve their punishment if they have trampled underfoot the Son of God, if they have disregarded the blood that sealed the agreement and makes us holy, treating it as ordinary and trivial, and have abused the Spirit of grace?
