Leviticus

And they came to the place which God had told him of; and Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood.

And the fire upon the altar shall be burning in it; it shall not be put out: and the priest shall burn wood on it every morning, and lay the burnt offering in order upon it; and he shall burn thereon the fat of the peace offerings.

The fire shall ever be burning upon the altar; it shall never go out.

Who is there even among you that would shut the doors for nought? neither do ye kindle fire on mine altar for nought. I have no pleasure in you, saith the Lord of hosts, neither will I accept an offering at your hand.

Now when Solomon had made an end of praying, the fire came down from heaven, and consumed the burnt offering and the sacrifices; and the glory of the Lord filled the house.
