Psalm 81:10 (NRSV)
“I am the Lord your God,
Who brought you up from the land of Egypt.
Open your mouth wide and I will fill it.
1 Corinthians 2:3-5 (AMP)
I came to you in [a state of] weakness and fear and great trembling. 4 And my message and my preaching were not in persuasive words of wisdom [using clever rhetoric], but [they were delivered] in demonstration of the [Holy] Spirit [operating through me] and of [His] power [stirring the minds of the listeners and persuading them], 5 so that your faith would not rest on the wisdom and rhetoric of men, but on the power of God.
Mark 3:28-30 (AMP)
“I assure you and most solemnly say to you, all sins will be forgiven the sons of men, and all the abusive and blasphemous things they say; 29 but whoever blasphemes against the Holy Spirit and His power [by attributing the miracles done by Me to Satan] never has forgiveness, but is guilty of an everlasting sin [a sin which is unforgivable in this present age as well as in the age to come]”— 30 [Jesus said this] because the scribes and Pharisees were [attributing His miracles to Satan by] saying, “He has an unclean spirit.”
