'Sovereign' in the Bible

They cried out in a loud voice, "Holy and true Sovereign, how long will it be before you judge and take revenge on those living on the earth who shed our blood?"

And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying,“Great and wonderful and awe-inspiring are Your works [in judgment],O Lord God, the Almighty [the Omnipotent, the Ruler of all];Righteous and true are Your ways,O King of the nations!
