>>> Signs does not refer to mystical heebee-jeebees.
LoL... you should do your research before embarrassing yourself like that.
The Hebrew translation is “owth” (Sign)
It is used for the following:
a distinguishing mark
banner
remembrance
miraculous sign
omen
warning
So YES... it does mean “mystical heebee jeebees as you put it.
Then you should not tempt God.
Deuteronomy 4:19 And beware lest you raise your eyes to heaven, and when you see the sun and the moon and the stars, all the host of heaven, you be drawn away and bow down to them and serve them, things that the Lord your God has allotted to all the peoples under the whole heaven.
Deuteronomy 18:10-12 There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the Lord. And because of these abominations the Lord your God is driving them out before you.
