Neglected Dicipline

Numbers 3:4 And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father.

Nadab and Abihu had not in their youth been trained to habits of self-control. The father's yielding disposition, his lack of firmness for right, had led him to neglect the discipline of his children.... Habits of self-indulgence, long cherished, obtained a hold upon them which even the responsibility of the most sacred office had not power to break. They had not been taught to respect the authority of their father, and they did not realize the necessity of exact obedience to the requirements of God. Aaron's mistaken indulgence of his sons prepared them to become the subjects of the divine judgments. {PP 360.1}
