Leviticus 1 gives the burnt offering from the worshiper-facing side: selection, presentation, slaughter, arrangement, and burning. Leviticus 6:8–13 revisits that same offering from the priests’ operational perspective, emphasizing the overnight altar fire, ash removal, priestly garments, and the requirement that the fire never go out.

Exodus 29 institutes the regular morning and evening burnt offering; Leviticus 6 gives priest-facing instructions that keep the burnt offering and altar fire continually maintained. The later law develops the daily sanctuary rhythm rather than introducing an unrelated sacrifice.

Leviticus 9:24 records divine fire consuming the inaugural offering. Later interpreters often connect that event with the command to preserve continual altar fire, but the text does not explicitly say the same supernatural flame was preserved forever.
