2 Chronicles 23:11

Then they brought out the king's son, from his place of concealment somewhere in the Temple chambers, and put upon him the crown, and gave him the testimony, either a copy of the entire Law, or of that part which related to the duties of a king, Deuteronomy 17:18, and made him king. And Jehoiada and his sons anointed him and said, God save the king! literally, "May the king live!" an acclamation of loyalty. After days of darkness and affliction the Lord often sends days of special joy and blessing upon His people.
