'Ruler' in the Bible

But the man who was injuring his neighbor pushed Moses away, saying, ‘Who appointed you ruler and judge over us?

“This Moses whom they rejected, saying, ‘Who made you a ruler and a judge?’ is the very one whom God sent to be both a ruler and a deliverer, with the [protecting and helping] hand of the Angel who appeared to him in the thorn bush.

And at once an angel of the Lord struck him down because he did not give God the glory [and instead permitted himself to be worshiped], and he was eaten by worms and died [five days later].

Paul said, “I was not aware, brothers, that he was high priest; for it is written, ‘You shall not speak evil of a ruler of your people.’”
