RASHNESS PUNISHED; REVERENCE BLESSED

Rashness Punished; Reverence Blessed. The LORD struck down some of the men of Beth-shemesh because they had looked into the ark of the LORD. He struck down 50,070 men among the people, and the people mourned because the LORD had struck the people with a great slaughter

CENSUS OF THE NEW GENERATION

Then it happened after the plague that the LORD said to Moses and Eleazar the son of Aaron the priest,
“Take a census of all the [males in the] congregation of the sons of Israel from twenty years old and upward, by their fathers’ households, all in Israel who are able to go to war.”

EDOM REFUSES PASSAGE; AARON DIES

Edom refuses passage; Aaron dies. But the king of Edom said, “You shall not pass through [my territory].” And Edom came out against Israel with many people and a strong hand.
Thus [the king of] Edom refused to give Israel passage through his territory, so Israel turned away from him.

THE DEATH OF NADAB AND ABIHU

Now Nadab and Abihu, the sons of Aaron, took their respective [ceremonial] censers, put fire in them, placed incense on it and offered strange (unauthorized, unacceptable) fire before the LORD, [an act] which He had not commanded them to do.
And fire came out from the presence of the LORD and devoured them, and they died before the LORD.
