Marcos 5:6-7

The way the man related to Jesus shows that the demons within him recognized Jesus as someone superior to them. The demons controlled the man’s physical movements and his words. They addressed Jesus as "Son of the Most High God" recognizing His deity (Genesis 14:18-24; Numbers 24:16; Isaiah 14:14; Daniel 3:26; Daniel 4:2; cf. Mark 1:23-24). The fact that the man knelt before Jesus likewise shows that the demons regarded Jesus as their superior. The demons feared that Jesus would send them to their eternal judgment then, something only God could do (Revelation 20:1-3; cf. Matthew 8:29; Luke 8:31). The tormentor appealed for deliverance from torment. [Note: R. Jamieson, A. R. Fausset, and D. Brown, A Commentary Critical and Explanatory on the Old and New Testaments, 2:70.] Ironically he appealed to Jesus for mercy in God’s name. He probably did this because he knew that Jesus was subject to His Father.
