Mark 9:25  (King James Version)
When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.

he rebuked
1:25-27 Mark 5:7 Mark 5:8 Zechariah 3:2 ; Matthew 17:18 ; Luke 4:35 Luke 4:41 ; 9:42 Jude 1:9

If this had been only a natural disease, as some have contended, could our Lord with any propriety have thus addressed it? If the demoniacal possession had been false, or merely a vulgar error, would our Lord, the Revealer of truth, have thus established falsehood, sanctioned error, or encouraged deception, by teaching men to ascribe effects to the malice and power of evil spirits, which they had no agency in producing? Impossible! Such conduct is utterly unworthy the sacred character of the Redeemer.
