'Ruler And Judge' in the Bible

But the one who was trying to harm his neighbor pushed Moses away saying, 'Who gave you the right to act as a ruler and judge over us?

But the Hebrews refused [to acknowledge Moses as their leader], saying, 'Who made you a ruler and judge [over us]?' [Nevertheless], God sent him [to Egypt] to be both a ruler and liberator [of the people] through the direction of [His] angel who appeared [to Moses] from the bush.
