oh that's a bit of a story.
I'm a bit of a literary geek & a religious geek. Not that I'm religious, just that religions in general fascinate me. Most of all the stories.
For example the story of Lilith.
Lilith is believed in Christianity and Judaism to have been "the mother demon" or "the night demon" (besides a couple other stories who claim other things, i.e. her being Adam's first wife)
She is/was believed to come to childrens' homes at night to kill/take/eat them...
.. Unless the parents hung four amulets above the baby's crib. One bearing the words 'Lilith - abi!" which translates to "Lilith - begone!" Or simply "Lilith go away".
((if you're interested in even more lore: when she left Adam and the Garden of Eden three angels were sent after her, their names fill the remaining three amulets.))
Lilith abi is what eventually became our modern word 'lullaby' which explains the dark nature of the seemingly sweet songs we sing for our infants.
My own take on the words, creating Lilithbye, is because I like the simplicity of the modern translation 'lilith go away' and because it's a combination between lilith abi and lullaby.
Well I hope that cleared it up. Thanks for asking xx
