Esh Okhlah

Out of the blue I thought of a Name used for God in the bible that a while ago had been quite important to me. All I remembered was that the Name started with OKH but not the whole word or the meaning of it. 
No problem for Google though; I found it:

Esh Okhlah (EISH oh-khe-LAH) consuming fire

I used to be fascinated by the thought that God is called consuming fire and jealous.
