# confess over him
"confess over the goat"
# he must put that sinfulness on the head of the goat
Aaron's actions here were a symbolic transfer of the people's sin to the goat as a sign that the goat would bear the punishment for their guilt. (See: [[rc://en/ta/man/jit/translate-symaction]])
# evil deeds ... rebellion ... sins
These all mean basically the same thing. Aaron is confessing every kind of sin that the people committed.
