Quoting: B1LLY The deceased were buried with an
obolus, placed in the mouth of the corpse, in order that, once a dead person's shade reached the underworld of Hades, it would be able to pay Charon for passage across the river Acheron. Legend had it that those without enough wealth, or whose friends refused to follow proper burial rites, were forced to wander the banks of the Acheron for one hundred years...

Note:
The word "obolos", also "obelos" or "odelos" in other dialects, means a long thin metal nail or rod, such as a spit.
In other words "obelisk"...

Therefore, an Obelisk could be a symbol of a 'price to be paid' or 'sacrifice'.

Ahem...
The Hebrew letter VAV means nail or
HOOK.
A VAV looks like the masonic square the person in the center is holding...

Children placed on top of a VAV are in danger of being "hooked"...


Vav is used in the Hebrew language as the conjunction "and", which ties well with its other meanings "Hook or Nail" as the "link" between the "above" and the "below"... (great work).
In order to make the "Sand" vibrate into the proper frequency... you need the right "Hook".
