'Ruler's' in the Bible

He kept for himself the first part, for his was the ruler's right: he put in force the righteousness of the Lord, and his decisions for Israel.

Out of Ephraim they came down into the valley; after you, Benjamin, among your tribesmen; from Machir came down the captains, and from Zebulun those in whose hand is the ruler's rod.

And fire has gone out from her rod, causing the destruction of her branches, so that there is no strong rod in her to be the ruler's rod of authority. This is a song of grief, and it was for a song of grief.

And when Jesus came into the ruler's house and saw the players with their instruments and the people making a noise,

Then the ruler's armed men took Jesus into the open square, and got all their band together.

And if this comes to the ruler's ears, we will see that he does not make you responsible.
