The Legends of the Jews
By Louis Ginzberg 
This is a massive collation of the Haggada--the traditions which have grown up surrounding the Biblical narrative. These stories and bits of layered detail are scattered throughout the Talmud and the Midrash, and other sources, including oral.
Immanuel Velikovsky who worked alongside others to establish the Hebrew University in Jerusalem wrote in his controversial book ‘Worlds in Collision’, that when Nadab and Abihu the sons of the high priest Aaron, who unprepared offered ‘strange fire’ before the Ark were both killed when lightening went up their noses and burnt a hole in their faces, causing injuries so severe that they had to be hidden from the community by wrapping the bodies in their tunics, for fear that the sight of them may have caused a rebellion against the god of Moses.
Abba Jose ben Dosetai taught that that Nadab and Abihu died in Leviticus 10:2 when two streams of fire came forth from the Holy of Holies and divided into four streams, of which two flowed into the nose of one and two into the nose of the other, so that their breath was burned up, but their garments remained untouched (as implied in Leviticus 10:5). (Sifra Shemini Mekhilta deMiluim 99:5:7;Babylonian Talmud Sanhedrin 52a.)
