The fire shall ever be burning upon the altar; it shall never go out.
All Commentaries on Leviticus 6:13 Go To Leviticus 6

AD 1781
The perpetual fire: This fire came from heaven, (infra. chap. 9. 24,) and was always kept burning on the altar, as a figure of the heavenly fire of divine love, which ought to be always burning in the heart of a Christian.
