'Authority' in the Bible

And he who overcomes [the world through believing that Jesus is the Son of God] and he who keeps My deeds [doing things that please Me] until the [very] end, to him I will give authority and power over the nations;

So I looked, and behold, an ashen (pale greenish gray) horse [like a corpse, representing death and pestilence]; and its rider’s name was Death; and Hades (the realm of the dead) was following with him. They were given authority and power over a fourth part of the earth, to kill with the sword and with famine and with plague (pestilence, disease) and by the wild beasts of the earth.

Then I saw another angel coming up from the rising of the sun, holding the seal of the living God; and with a loud voice he called out to the four angels to whom it was granted [to have authority and power] to harm the earth and the sea,

Then I heard a loud voice in heaven, saying,“Now the salvation, and the power, and the kingdom (dominion, reign) of our God, and the authority of His Christ have come; for the accuser of our [believing] brothers and sisters has been thrown down [at last], he who accuses them and keeps bringing charges [of sinful behavior] against them before our God day and night.

They fell down and worshiped the dragon because he gave his authority to the beast; they also worshiped the beast, saying, “Who is like (as great as) the beast, and who is able to wage war against him?”

And the beast was given a mouth (the power of speech), uttering great things and arrogant and blasphemous words, and he was given freedom and authority to act and to do as he pleased for forty-two months (three and a half years).

He was also permitted to wage war against the saints (God’s people) and to overcome them, and authority and power over every tribe and people and language and nation.

And another angel came from the altar, the one who has power over fire; and he called with a loud voice to him who had the sharp sickle, saying, “Put in your sharp sickle and reap the clusters of grapes from the vine of the earth, because her grapes are ripe [for judgment].”

The ten horns that you saw are ten kings who have not yet received a kingdom, but [together] they receive authority as kings for a single hour [for a common purpose] along with the beast.

These [kings] have one purpose [one mind, one common goal], and they give their power and authority to the beast.

For God has put it in their hearts to carry out His purpose by agreeing together to surrender their kingdom to the beast, until the [prophetic] words of God will be fulfilled.

After these things I saw another angel coming down from heaven, possessing great authority, and the earth was illuminated with his splendor and radiance.

After these things I heard something like the great and mighty shout of a vast multitude in heaven, exclaiming,“Hallelujah! Salvation and glory (splendor, majesty) and power (dominion, might) belong to our God;

And then I saw thrones, and sitting on them were those to whom judgment [that is, the authority to act as judges] was given. And I saw the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had refused to worship the beast or his image, and had not accepted his mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years.

Blessed (happy, prosperous, to be admired) and holy is the person who takes part in the first resurrection; over these the second death [which is eternal separation from God, the lake of fire] has no power or authority, but they will be priests of God and of Christ and they will reign with Him a thousand years.

Blessed (happy, prosperous, to be admired) are those who wash their robes [in the blood of Christ by believing and trusting in Him—the righteous who do His commandments], so that they may have the right to the tree of life, and may enter by the gates into the city.
