'Princes' in the Bible

If you do this, then the kings and princes who follow in David's succession and ride in chariots or on horses will continue to enter through these gates, as well as their officials and the people of Judah and the citizens of Jerusalem. This city will always be filled with people.

He also ordered Jerahmeel, who was one of the royal princes, Seraiah son of Azriel, and Shelemiah son of Abdeel to arrest the scribe Baruch and the prophet Jeremiah. However, the Lord hid them.

So the officials took Jeremiah and put him in the cistern of Malkijah, one of the royal princes, that was in the courtyard of the guardhouse. There was no water in the cistern, only mud. So when they lowered Jeremiah into the cistern with ropes he sank in the mud.
