'Privately' in the Bible

Then King Zedekiah had him brought to the palace. There he questioned him privately and asked him, "Is there any message from the Lord?" Jeremiah answered, "Yes, there is." Then he announced, "You will be handed over to the king of Babylon."

Then Johanan son of Kareah spoke privately to Gedaliah there at Mizpah, "Let me go and kill Ishmael the son of Nethaniah before anyone knows about it. Otherwise he will kill you and all the Judeans who have rallied around you will be scattered. Then what remains of Judah will disappear."
