The demon-possessed man was probably incapable of coming to Jesus by himself; thus, he "was brought to Him." It is likely that the demon which possessed him was responsible for his inability to see and speak. Jesus, with His divine power, easily "healed" the man. Either our Lord drove the demon out and the man's sight and speech were automatically restored, or He drove the demon out and miraculously gave him the ability to see and speak.
"The multitudes were amazed" at this awesome work Jesus performed right before their eyes! One moment this man was just a shell of a human being and then suddenly his deficiencies were removed and he was able to see and speak! The crowd of onlookers was so impressed by what they witnessed that it even caused them to question who this miracle worker was. Could this be the Son of David? Could this Jesus be the Messiah?
Although the crowd reacted to this miracle with amazement and wonder, the Pharisees and scribes (cf. Mark 3:22) reacted in just the opposite way! According to Matthew 12:14, the Pharisees were already plotting to kill Jesus. They were envious of Him because of His great popularity. But, what could they do in a situation like this? They couldn't deny the miracle because everyone there had witnessed it. So their only option was to attempt to weaken or destroy the effect this miracle had on the people. They hoped to do this by coming up with an explanation that might sound plausible to the crowd. They stated that Jesus was able to perform this miracle by the power of "Beelzebub" and not by the power of God!
The word Beelzebub is a corruption of the name Baal-Zebub. This was the Philistine god of the fly (cf. II Kings 1). It was common for heathens to name their gods after pests they hoped the god would eliminate. It is not known how Beelzebub came to be identified with Satan in the Jewish culture (cf. 12:26).
Essentially, the scribes and Pharisees are trying to make Jesus lose His credibility by saying His power is from Satan, not God. They probably believe that this will be a difficult charge for Him to disprove.
According to Luke 11:16, there were others who were present who tested Him, seeking a sign from heaven. These individuals may have hoped Jesus would silence His opposition by showing some great sign, such as the pillar of cloud which had sanctioned the leadership of Moses (Num. 12) or the descending fire which had vindicated Elijah (II Kings 1). However, Jesus will do nothing of the sort. Instead He will respond to the blasphemy of the scribes and Pharisees with three distinct arguments that expose the absurdity of their claim that His power is from Satan. We will consider these points tomorrow.
