10:1 And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered {a} strange fire before the LORD, which he commanded them not.
(a) Not taken from the altar, which was sent from heaven, and endured till the captivity of Babylon.
10:1 Strange fire - Fire so called, because not taken from the altar, as it ought, but from some common fire. Before the Lord - Upon the altar of incense. Which he commanded not - Not commanding may be here put for forbidding, as it is, Jer 32:35. Now as this was forbidden implicitly; Lev 6:12, especially when God himself made a comment upon that text, and by sending fire from heaven declared of what fire he there spake; so it is more than probable it was forbidden expressly, though that be not here mentioned, nor was it necessary it should be.
10:1,2 Next to Moses and Aaron, none were more likely to be honourable in Israel than Nadab and Abihu. There is reason to think that they were puffed up with pride, and that they were heated with wine. While the people were prostrate before the Lord, adoring his presence and glory, they rushed into the tabernacle to burn incense, though not at the appointed time; both together, instead of one alone, and with fire not taken from the altar. If it had been done through ignorance, they had been allowed to bring a sin-offering. But the soul that doeth presumptuously, and in contempt of God's majesty and justice, that soul shall be cut off. The wages of sin is death. They died in the very act of their sin. The sin and punishment of these priests showed the imperfection of that priesthood from the very beginning, and that it could not shelter any from the fire of God's wrath, otherwise than as it was typical of Christ's priesthood.
