Abihu - father of Him; i.e., "worshipper of God", the second of the sons\nof Aaron (Ex. 6:23; Num. 3:2; 26:60; 1 Chr. 6:3). Along with his\nthree brothers he was consecrated to the priest's office (Ex.\n28:1). With his father and elder brother he accompanied the\nseventy elders part of the way up the mount with Moses (Ex.\n24:1,9). On one occasion he and Nadab his brother offered\nincense in their censers filled with "strange" (i.e., common)\nfire, i.e., not with fire taken from the great brazen altar\n(Lev. 6:9, etc.), and for this offence they were struck dead,\nand were taken out and buried without the camp (Lev. 10:1-11;\ncomp. Num. 3:4; 26:61; 1 Chr. 24:2). It is probable that when\nthey committed this offence they were intoxicated, for\nimmediately after is given the law prohibiting the use of wine\nor strong drink to the priests.
