'Crown' in the Bible

And Rehoboam appointed Abijah the son of Maacah as chief and crown prince over his brothers, in order to make him king.

"So now you think you'll be able to withstand the LORD's kingdom as controlled by David's descendants, just because you have a large crown and have brought with you the golden calves that Jeroboam made for you as gods.

Then they brought out the king's son, and put upon him the crown, and gave him the testimony, and made him king. And Jehoiada and his sons anointed him, and said, God save the king.
