Matthew 10:21 (KJV), He says:
"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."
Similarly, in Mark 13:12 (KJV), He reiterates:
"Now the brother shall betray the brother to death, and the father the son; and children shall rise up against their parents, and shall cause them to be put to death."
This aligns with the broader theme that in the last days, there will be great deception, persecution, and even betrayal within families as the world turns against true followers of Christ.
