'Public' in the Bible

“When someone sins in any of these ways: If he has seen, heard, or known about something he has witnessed, and did not respond to a public call to testify, he is responsible for his sin.

And Aaron, placing his two hands on the head of the living goat, will make a public statement over him of all the evil doings of the children of Israel and all their wrongdoing, in all their sins; and he will put them on the head of the goat and send him away, in the care of a man who will be waiting there, into the waste land.
