'Power' in the Bible

when all at once, there in their synagogue, a man under the power of a foul spirit screamed out:

The Scribes, too, who had come down from Jerusalem said, "He has Baal-zebul in him; and it is by the power of the Prince of the demons that he expels the demons."

Immediately Jesus, well knowing that healing power had gone from within Him, turned round in the crowd and asked, "Who touched my clothes?"

He went on to say, "In solemn truth I tell you that some of those who are standing here will certainly not taste death till they have seen the Kingdom of God already come in power."

and wherever it comes upon him, it dashes him to the ground, and he foams at the mouth and grinds his teeth, and he is pining away. I begged your disciples to expel it, but they had not the power."

"Is not this the cause of your error," replied Jesus--"your ignorance alike of the Scriptures and of the power of God?

And then will they see the Son of Man coming in clouds with great power and glory.

"I am," replied Jesus, "and you and others will see the Son of Man sitting at the right hand of the divine Power, and coming amid the clouds of the sky."
