The verse is from the showdown between Elijah for YHWH, and the priests of Ba'al/priestesses of Ashteroth.
The Jews were following foreign gods, which culminated in the prophet challenging the pagans to a duel.
Twin sacrifices, whoever's god calls down fire from heaven wins.
Ba'al priests failed; hysterics, cutting themselves, yelling, shouting, "praying", nada.
Elijah taunted them to pray louder; maybe their demon god was asleep, or on the privy.
When it was Elijah's turn, he doused his sacrifice in water, prayed, and fire from heaven immediately consumed both sacrifices.
Elijah then walked the priests of Ba'al down to the river, and had their throats slit.
Choose this day whom ye will serve.
You are not promised tomorrow.
Most Anons are going into eternal hellfire.
I say this to my shame.
