It is common, in Florida, to use your grill all year long. We use ours almost every day because I don’t like to keep smelling my food all night long. When you cook on the grill, drippings and such will fall through the grate and eventually become ashes. If you leave your meat on the grill too long on high heat, your meat will also become ashes!
There is a scripture in Revelation that describes the martyrs who are under the altar, crying out for vengeance for the shedding of their blood on earth. They were killed because of the word of God, and because of the testimony they held. I never understood why they were under the altar! Now I do! The alter is a grill! These martyrs were sacrificed, and their souls are like ashes under the grill. I never put two and two together until I started studying the Old Testament, and Exodus.
The martyrs were given white robes and were told to rest, and wait for the full number of those killed, as they had been killed. Jesus has made sure they are comfortable until he avenges their deaths.
Practical use for this today: Always refer back to the New Testament when studying the Old Testament, and vice versa, they go together hand in hand.
When he opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the witness they had borne. Revelation 6:9
You shall make pots for it to receive its ashes, and shovels and basins and forks and fire pans. You shall make all its utensils of bronze. You shall also make for it a grating, a network of bronze, and on the net you shall make four bronze rings at its four corners. Exodus 27:3-4
