Hisgalus 13:16-18

Orthodox Jewish Bible

¹⁶ And it causes all, the Ketanim (small) and the Gedolim (great), both the oishir (rich) and aniyim (poor), the bnei Chorin (freedmen) and avadim (slaves), that to them should be given a tav [mark] on the yad yamin (right hand) and on the metsakh (forehead) of them, [YECHEZKEL 9:4]

¹⁷ And that no one should be able to buy or to sell except the one having the tav [mark], the name of the Chayyah (Beast, Anti-Moshiach) or the number of its name.

¹⁸ Here is chochmah: the one having binah, let him do the gematria and get the mispar (number) of the Chayyah (Anti-Moshiach), for it is the mispar (number) of a man, and the mispar of it is SHESH ME’OT V’SHISHIM VASHESH (666).
