What does Leviticus 16:21 mean?

He puts both hands on the goat’s head and confesses all the ways the Israelites have messed up, all their wrongs and failures. He puts all of it on the goat, then sends it away into the desert with someone who’s ready for the job. Leviticus 16:21 - Modern Text Bible

(This is a powerful symbol: all the people’s guilt is placed on the goat, which is then sent far away, showing that their sins are being removed.)
