daily incense-offering. By the fire which they offered before Jehovah, we are no doubt to understand the firing of the incense-offering. This might be called “strange fire” if it was not offered in the manner prescribed in the law, just as in Exo 30:9 incense not prepared according to the direction of God is called “strange incense.” The supposition that they presented an incense-offering that was not commanded in the law, and apart from the time of the morning and evening sacrifice, and that this constituted their sin, is supported by the time at which their illegal act took place. It is perfectly obvious from Lev 10:12. and 16ff. that it occurred in the interval between the sacrificial transaction in ch. 9 and the sacrificial meal which followed it, and therefore upon the day of their inauguration. For in Lev 10:12 Moses commands Aaron and his remaining sons Eleazar and Ithamar to eat the meat-offering that was left from the firings of Jehovah, and inquires in Lev 10:16 for the goat of the sin-offering, which the priests were to have eaten in a holy place. Knobel's opinion is not an improbable one, therefore, that Nadab and Abihu intended to accompany the shouts of the people with an incense-offering to the praise and glory of God, and presented an incense-offering not only at an improper time, but not prepared from the altar-fire, and committed such a sin by this will-worship, that they were smitten by the fire which came forth from Jehovah, even before their entrance into the holy place, and so died “before Jehovah.” The expression “before Jehovah” is applied to the presence of God, both in the dwelling (viz., the holy place and the holy of holies, e.g., Lev 4:6-7; Lev 16:13) and also in the court (e.g., Lev 1:5, etc.). It is in the latter sense that it is to be taken here, as is evident from Lev 10:4, where the persons slain are said to have lain “before the sanctuary of the dwelling,” i.e., in the court of the tabernacle. The fire of the holy God (Exo 19:18), which had just sanctified the service of Aaron as well-pleasing to God, brought destruction upon his two eldest sons, because they had not sanctified Jehovah in their hearts, but had taken upon themselves a self-willed service; just as the same gospel is to one a savour of life unto life, and to another a savour of death unto death (2Co 2:16). - In Lev 10:3 Moses explains this judgment to Aaron: “This is it that Jehovah spake, saying, I will sanctify Myself in him that is nigh to Me, and will glorify Myself
