'Secrecy' in the Bible

Then King Zedekiah sent and fetched him. And the king questioned him in secrecy in his house, and he said, "Is there a word from Yahweh?" And Jeremiah said, "There is." And he said, "You will be given into the hand of the king of Babylon."

Then Johanan the son of Kareah said to Gedaliah in secrecy at Mizpah, {saying}, "Please let me go and kill Ishmael the son of Nethaniah, and {nobody} will know. Why should he kill you, so that all of Judah who are gathered to you will be scattered, and the remnant of Judah will perish?"
