Hesabu 3 : 4 Numbers chapter 3 verse 4

Kisha Nadabu na Abihu walikufa mbele za Bwana, waliposongeza moto wa kigeni mbele za Bwana, katika bara ya Sinai, nao walikuwa hawana wana; na Eleazari na Ithamari wakafanya kazi ya ukuhani mbele ya uso wa Haruni baba yao.

Nadab and Abihu died before Yahweh, when they offered strange fire before Yahweh, in the wilderness of Sinai, and they had no children. Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father.
