Leviticus 6:13

13. The fire shall ever be burning upon the altar This altar-fire was of a supernatural origin, (Leviticus 9:24,) as the fire of love to God in a fallen soul is not spontaneously ignited, but is a spark dropped from above. The fire on the altar, as the symbol of Jehovah’s holiness and the instrument of his purifying or destroying power, was the only fire permitted to be used in the tabernacle. That obtained elsewhere for sacred purposes was called “strange.” Leviticus 10:1. According to the Gemera the sacred fire was divided into three parts, one for burning victims, one for incense, and one for the supply of the other portions. “According to the Jewish legends, this sacred fire was kept up without interruption till the Babylonian captivity, and, according to 2Ma 1:19 , till a period later.

The Talmud and many rabbins reckon it as one of the five things which were wanting in the second temple the fire, the ark, the urim and thummim, the anointing oil, and the spirit of holiness.” Kurtz. The injunction to keep the fire always burning enforces the duty of undying zeal in the service of Christ through the Holy Spirit ever abiding within as a refiner’s fire. The wood laid on the fire every morning typifies the means of grace daily used, the Holy Scriptures, prayer and praise.
