Abihu

From BibleEncyclopedia.Net

a-bī´hū (אביהוּא, 'ăbhīhū), “father he is,” or “my father he is,” or "Father of Him," i.e., “worshipper of God”):

The second of the sons of Aaron, the high priest (Exodus 6:23; Numbers 3:2; Numbers 26:60; 1 Chronicles 6:3). Along with his three brothers he was consecrated to the priest's office (Exodus 28:1). With his father and elder brother he accompanied the seventy elders part of the way up the mount with Moses (Exodus 24:1, Exodus 24:9). On one occasion he and Nadab his brother offered incense in their censers filled with “strange” (i.e., common) fire, i.e., not with fire taken from the great brazen altar (Leviticus 6:9, etc.), and for this offense they were struck dead, and were taken out and buried without the camp (Leviticus 10:1-11; compare Numbers 3:4; Numbers 26:61; 1 Chronicles 24:2). It is probable that when they committed this offense they were intoxicated, for immediately after is given the law prohibiting the use of wine or strong drink to the priests.

With his older brother Nadab he “died before YHWH,” when the two “offered strange fire” (Leviticus 10:1, Leviticus 10:2). It may be inferred from the emphatic prohibition of wine or strong drink, laid upon the priests immediately after this tragedy, that the two brothers were going to their priestly functions in an intoxicated condition (Leviticus 10:8-11). Their death is mentioned three times in subsequent records (Numbers 3:4; Numbers 26:61; 1 Chronicles 24:2).
