'Authority' in the Bible

You put all things under his feet. For in making man the ruler over all things, God did not put anything outside his authority; though we do not see everything under him now.

Since then the children referred to are all alike sharers in perishable human nature, He Himself also, in the same way, took on Him a share of it, in order that through death He might render powerless him who had authority over death, that is, the Devil,

but Christ was faithful as a Son having authority over God's house, and we are that house, if we hold firm to the End the boldness and the hope which we boast of as ours.

And no man who is not given authority by God, as Aaron was, takes this honour for himself.

Now every high priest is given authority to take to God the things which are given and to make offerings; so that it is necessary for this man, like them, to have something for an offering.

and since we have a great Priest who has authority over the house of God,

And again, if the fathers of our flesh gave us punishment and had our respect, how much more will we be under the authority of the Father of spirits, and have life?

Remember your leaders [for it was they] who brought you the word of God; and consider the result of their conduct [the outcome of their godly lives], and imitate their faith [their conviction that God exists and is the Creator and Ruler of all things, the Provider of eternal salvation through Christ, and imitate their reliance on God with absolute trust and confidence in His power, wisdom, and goodness].

we have an altar, of which to eat they have no authority who the tabernacle are serving,

Obey your [spiritual] leaders and submit to them [recognizing their authority over you], for they are keeping watch over your souls and continually guarding your spiritual welfare as those who will give an account [of their stewardship of you]. Let them do this with joy and not with grief and groans, for this would be of no benefit to you.
