Miracle of the fire - Zevachim 89

Our Mishna says that one must first burn the limbs of an ‘olah and then the parts of a chatas. At the inauguration of the altar in the Sanctuary, the Torah says that they put the ‘olah on the altar and, above it, the parts of the other sacrifices (Vayikra 9). But when the fire came out from before Hashem and “consumed on the altar”, the verse says that it consumed the “’olah and the fats.” In other words, first the fire burned the ‘olah and then the fats above the ‘olah! The Netziv writes that this was a miracle to observe the halachah that the limbs of an ‘olah are burnt before the parts of other sacrifices (Ha’amek Davar, Shemini).
