'Ruler's' in the Bible

“The scepter shall not depart from Judah,Nor the ruler’s staff from between his feet,Until Shiloh comes,And to him shall be the obedience of the peoples.

“Then he provided the first part for himself,For there the ruler’s portion was reserved;And he came with the leaders of the people;He executed the justice of the Lord,And His ordinances with Israel.”

Many seek the ruler’s favor,But justice for man comes from the Lord.

If the ruler’s temper rises against you, do not abandon your position, because composure allays great offenses.
