Oboy...
This is indeed how superstitions start, make no mistake about it. Everything you read here will be "out-of-context" cuz it's a LONG passage, but this snippet will have to do. Don't any of you OWN a Bible? It'll keep you from cultic shenanigans, if you read it!
Here's the quote, comments pertinent to this discussion follow. I start with the "Sword part", cuz, well, i want to... Revelation 13:14b-18:
"...an image to the beast, which had the wound by a sword, and did live.
15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed.
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six."
Point 1- the mark of the beast is on the hand or forehead, not on "yo' knife!"
Point 2- the beast controls the free market; so you can't sell anything without his approval, his mark. Knives are great, but it's hard to control everyone with just a knife...
Point 3- "the number of the beast ... it is the number of a man." NOT a knife...
For all you know, this could be the knife {sword includes knife in Scripture} that puts that head-wound in the Tyrant, & because he recovers, he "adopts" the number as "his own" just for kicks...!
My advice: FACE your Fears, BUY the Knife; if you don't like it, send it to Mick Strider; if anyone could take out a bad guy with it, it'd be him...!
{Always cheering for ya' Mick...}
You might get a real Strider out of the deal, & he'd get one heckuva adventure!
For the record, Thousands of items are numbered in society; i've run across 666 on things at least a hundred verifiable times.
No worries. "Pastor" Clif, happy to help.
