Leviticus 6:9

And the Lord spake — Hitherto he hath prescribed the sacrifices themselves; now he comes to the manner of them. The burnt — offering — The daily one, which Exodus 29:38, Numbers 28:3, as the following words shew. This was to be so managed and laid on piece after piece, that the fire might be constantly maintained by it. The morning burnt — offerings were to be kept burning all the day from morning to night also; but he mentions not that, because there was such a constant succession of sacrifices in the day — time that there needed no law for feeding and keeping in the fire then; the only danger was for the night, when other sacrifices were not offered, but only the evening burnt — offering, which if it had been consumed quickly, as the morning burnt — offering was, there had been danger of the going out of that fire, which they were commanded diligently and constantly to keep in.
