Matthew 10:34–36, Jesus said He had come at this time not to bring peace to the earth, but a sword, a weapon which divides and severs. As a result of His visit to the earth, some children would be set against parents and a man’s enemies might be those within his own household. This is because many who choose to follow Christ are hated by their family members.

Zec:13:8-9:
And it shall come to pass,
that in all the land,
saith the LORD,
two parts therein shall be cut off and die;
but the third shall be left therein.
And I will bring the third part through the fire,
and will refine them as silver is refined,
and will try them as gold is tried:
they shall call on my name,
and I will hear them:
I will say,
It is my people:
and they shall say,
The LORD is my God.
Isa:55:11:
So shall my word be that goeth forth out of my mouth:
it shall not return unto me void,
but it shall accomplish that which I please,
and it shall prosper in the thing whereto I sent it.
Re:19:21:
And the remnant were slain with the sword of him that sat upon the horse,
which sword proceeded out of his mouth:
and all the fowls were filled with their flesh.
Isa:65:12-14:
Therefore will I number you to the sword,
and ye shall all bow down to the slaughter:
because when I called,
ye did not answer;
when I spake,
ye did not hear;
but did evil before mine eyes,
and did choose that wherein I delighted not.
Therefore thus saith the Lord GOD,
Behold,
my servants shall eat,
but ye shall be hungry:
behold,
my servants shall drink,
but ye shall be thirsty: behold, my servants shall rejoice, but ye shall be ashamed:
Behold,
my servants shall sing for joy of heart,
but ye shall cry for sorrow of heart,
and shall howl for vexation of spirit.
