1 Kings 19:10

Who said it?....

I have been very zealous for Yahweh God of hosts;
for the children of Israel have forsaken Your covenant,
torn down Your altars,
and killed Your prophets with the sword.
I alone am left;
and they seek to take my life.

As verse 18 indicates, Elijah was not entirely correct when he spoke those words. But those words actually were entirely true of Someone else.

And golly jeepers, look at where Elijah was saying those words. At the mountain of God. And he spent the night in a cave. Hmmmm.....
