the Pharisees: they watch so that they might find an excuse to destroy Jesus.
great multitude: they want healing from sicknesses and deliverance from evil spirits.
unclean spirits: they fear Jesus and have to flee.
His own people; His brothers and His mother: they think He is out of His mind and bring shame to the family.
But Jesus is more concerned with the right persons watching Him: He said,
“whoever does the will of God is My brother and My sister and mother.”
Mark 3 New King James Version (NKJV) (quoted in parts; highlight added)
Healing on the Sabbath
3 And He entered the synagogue again, and a man was there who had a withered hand. 2 So they watched Him closely, whether He would heal him on the Sabbath, so that they might accuse Him.
6 Then the Pharisees went out and immediately plotted with the Herodians against Him, how they might destroy Him.
a great multitude, when they heard how many things He was doing, came to Him.
10 For He healed many, so that as many as had afflictions pressed about Him to touch Him. 11 And the unclean spirits, whenever they saw Him, fell down before Him and cried out, saying, “You are the Son of God.”
21 But when His own people heard about this, they went out to lay hold of Him, for they said, “He is out of His mind.”
31 Then His brothers and His mother came, and standing outside they sent to Him, calling Him. 32 And a multitude was sitting around Him; and they said to Him, “Look, Your mother and Your brothers[e] are outside seeking You.”
33 But He answered them, saying, “Who is My mother, or My brothers?” 34 And He looked around in a circle at those who sat about Him, and said, “Here are My mother and My brothers! 35 For whoever does the will of God is My brother and My sister and mother.”
