Star of David,
I second that.
Very next chapter, Rev. 14:1 "And I looked, and, lo, a Lamb stood on the mount Sion, and with him a hundred forty and four thousand, having his Father's name written in their foreheads."
So Jesus has a mark he gives out too. You get it by making a decision to follow him. Then he will make your forehead as strong as flint.
I need a bumper sticker that says Stubborn for Jesus.
I think Rev. 13:16 means he (the beast) will make a practice of giving "all"
a mark so that nobody will be able to buy or sell without his permission.
There's plenty of people at the end that don't take the bait, per Rev. 20:4. Speaking of bait, that's about all the devil gives out to eat. ie, worms, maggots, crickets.
