Leviticus 10:1-9

1 But Nadav and Avihu, sons of Aharon, each took his censer, put fire in it, laid incense on it, and offered unauthorized fire before ADONAI, something he had not ordered them to do.

6 Then Moshe told Aharon and his sons El'azar and Itamar, "Don't unbind your hair or tear your clothes in mourning, so that you won't die and so that ADONAI won't be angry with the entire community. Rather, let your kinsmen - the whole house of Isra'el -mourn, because of the destruction ADONAI brought about with his fire.
7 Moreover, don't leave the entrance to the tent of meeting, or you will die, because ADONAI's anointing oil is on you."

9 "Don't drink any wine or other intoxicating liquor, neither you nor your sons with you, when you enter the tent of meeting, so that you will not die. This is to be a permanent regulation through all your generations,
