A: The number 6 falls short of God's number 7.
So 6-6-6 is this world religious system falling short of God's perfection (man's ways/systems always do).
*Also, notice there are three in this system in the end .... out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
Revelation 16:13
