Matthew 10:32-34 (KJV)
32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
34 Think not that I am come to send peace on earth: I came not to send peace, but a sword.
Matthew 10:21,22 (KJV)
21 And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death.
22 And ye shall be hated of all men for my name’s sake: but he that endureth to the end shall be saved.
