New Defender's Study Bible Notes
10:1 censer. A container for burning incense.
10:2 fire from the LORD. Exactly what the “strange fire” offered by Nadab and Abihu may have been is not explained. This sudden judgment upon Aaron’s sons, however, stresses the critical importance of adherence to God’s Word, especially by those called to special service on behalf of the Lord. In some way, they had failed to obey God’s commands in connection with their priestly service. Therefore, God judged them as an example and warning against spiritual presumption on the part of any of His people. Note Leviticus 16:1-2.
