'Secretly' in the Bible

Now King Zedekiah sent and took him out; and in his palace the king secretly asked him and said, “Is there a word from the Lord?” And Jeremiah said, “There is!” Then he said, “You will be given into the hand of the king of Babylon!”

Then Johanan the son of Kareah spoke secretly to Gedaliah in Mizpah, saying, “Let me go and kill Ishmael the son of Nethaniah, and not a man will know! Why should he take your life, so that all the Jews who are gathered to you would be scattered and the remnant of Judah would perish?”
