'Ruler' in the Bible

And he said, Who made you a ruler and a judge over us? are you going to put me to death as you did the Egyptian? And Moses was in fear, and said, It is clear that the thing has come to light.

I let myself be seen by Abraham, Isaac, and Jacob, as God, the Ruler of all; but they had no knowledge of my name Yahweh.

You may not say evil of the judges, or put a curse on the ruler of your people.
