'Princes' in the Bible

Now when Jehoram had taken his place over his father's kingdom, and had made his position safe, he put all his brothers to death with the sword, as well as some of the princes of Israel.

Now when Jehu was effecting the punishment of the family of Ahab, he came to the princes of Judah and the sons of Ahaziah's brothers, the servants of Ahaziah, and put them to death.
