'Rulers' in the Bible

Now when Jehoram had taken over the kingdom of his father and made himself secure, he killed all his brothers with the sword, and some of the rulers of Israel also.

He took the captains of hundreds, the nobles, the rulers of the people and all the people of the land, and brought the king down from the house of the Lord, and came through the upper gate to the king’s house. And they placed the king upon the royal throne.

When Hezekiah and the rulers came and saw the heaps, they blessed the Lord and His people Israel.

Even in the matter of the envoys of the rulers of Babylon, who sent to him to inquire of the wonder that had happened in the land, God left him alone only to test him, that He might know all that was in his heart.
