Finally, Moses sprinkled the priestly clothes of Aaron and his sons with some of the oil for ordination and with some of the blood from the altar. So Aaron and his sons, together with their priestly clothes, were dedicated to the LORD.
But the LORD killed Nadab and Abihu in the Sinai Desert when they used fire that was unacceptable in their offering to the LORD. And because Nadab and Abihu had no sons, only Eleazar and Ithamar served as priests with their father Aaron.
The Law appoints priests who have weaknesses. But God's promise, which came later than the Law, appoints his Son. And he is the perfect high priest for ever.
