2 “Sanctify to me all the firstborn, whatever opens the womb among the children of Israel, both of man and of animal. It is mine.” Exodus 13:2WEB
This passage contains a positive command, directed toward Israel through Moses: "Sanctify to me all the firstborn, whatever opens the womb among the children of Israel, both of man and of animal. It is mine.".
This command is relevant to an understanding of Sacrifice because of the means by which firstborn animals can be offered to God, Inheritance because it pertains to the firstborn of the children of Israel, and Sanctification because the command is to sanctify the firstborn.
The command received fulfillment soon after it was given, when God took the Levites as a substitutionary offering in place of the firstborn of Israel (see Numbers 3:12,45). The command was then fulfilled by Jesus, who was a priest after the order of Melchizedek, superseding and replacing the Levitical priesthood (see Hebrews 6), and Jesus offered himself as a substitute on behalf of all mankind, being (as it says in Romans 8:29) the firstborn among many brothers.
