'Secretly' in the Bible

Jehosheba, who was King Jehoram’s daughter and Ahaziah’s sister, secretly rescued Joash son of Ahaziah from the king’s sons who were being killed and put him and the one who nursed him in a bedroom. So he was hidden from Athaliah and was not killed.

The Israelites secretly did what was not right against the Lord their God. They built high places in all their towns from watchtower to fortified city.
