--For all that do these things are an abomination unto the LORD: and because of these abominations the LORD thy God doth drive them out from before thee.
Deuteronomy 18:10-12
"According to Celtic tradition during Samhain, the veil between our
world and the “Otherworld” is broken, which enables spirits from the
dead to come back and visit the living. As part of Samhain, the Celts offered food, animals, and even people to the spirit world.
In addition to the spirit world being able to visit the real world, the Celts believed witches, goblins, fairies, and demons would be roaming around the earth and could visit the inhabitants of the earth.
The
Druids believed in order to appease the demons, witches, fairies, and
goblins,
---you had to leave them sweets
---or you had to dress up like them
in a costume in order to not be detected as a human being." Christian.com
