Many Christian groups believe in the so-called “mark of the beast”—a supposed mark or sign upon the forehead and hand of those who worship the image of the antichrist.
Revelation 13:16: “And the small and the great, and the rich and the poor, and the freemen and the slaves, it causes that they give to them all a mark on their right hand, or on their foreheads”Of course, this interpretation fails to recognize a Hebrew idiom--"a mark upon the hand/head." In the old testament this idiom has a simple meaning. To have "a mark upon the head" means to recall that which the mark stands for, namely God's word. To have "a mark upon the hand" means to be marked for the work of God's word.
Exo 13:9 "Moreover, it will serve you as a sign on your hand and as a reminder between your eyes, so that Yahweh's Law may be on your lips; because with a strong hand Yahweh brought you out of Egypt.Therefore, the reference to the "mark of the beast" in Revelation means:
Deu 11:18 Therefore, you are to store up these words of mine in your heart and in all your being; tie them on your hand as a sign; put them at the front of a headband around your forehead;
“And the small and the great, and the rich and the poor, and the freemen and the slaves, it causes that they give to them all to recall and do the work of his word.
