'Secret' in the Bible

If a person hides himself in secret places, will I not see him?" declares the LORD. "I fill the heavens and the earth, do I not?" declares the LORD.

Then King Zedekiah, in secret, swore an oath to Jeremiah: "As surely as the LORD lives, who gave us this life to live, I won't have you put to death, nor will I hand you over to these men who are seeking to kill you."
