Standing in front of them were seventy elders of the house of Israel, with Jaazaniah the son of Shaphan standing among them, each man with his censer in his hand and the fragrance of the cloud of incense rising.
And each of you take his firepan and put incense on it, and each of you bring his censer near before Yahweh, 250 firepans; also you and Aaron shall each bring his firepan.”
and they rose up before Moses, together with some of the sons of Israel, 250 leaders of the congregation, those called upon by the assembly, men of renown.
and the earth opened its mouth and swallowed them up along with Korah, when that congregation died, when the fire consumed 250 men, so that they became a warning.
But Nadab and Abihu died before Yahweh when they offered strange fire before Yahweh in the wilderness of Sinai; and they had no children. So Eleazar and Ithamar ministered as priests in the lifetime of their father Aaron.
And if anyone wishes to harm them, fire comes out of their mouth and devours their enemies; so if anyone wishes to harm them, he must be killed in this way.
