If it's just for Aron and his sons, why does it say "it is a permanent statute throughout your generations?"
The "tent of meeting" represents the Church. This is instruction to all of us, for when we attend Church.
Becoming divisive in your rhetoric doesn't honor God.
Read the context.
Everything you do not understand a bible passage read what it is saying g before and after that verse.
Lev 10:8 Then the Lord said to Aaron, 9 “You and your sons are not to drink wine or other fermented drink whenever you go into the tent of meeting, or you will die. This is a lasting ordinance for the generations to come, 10 so that you can distinguish between the holy and the common, between the unclean and the clean, 11 and so you can teach the Israelites all the decrees the Lord has given them through Moses.”
God is still speaking through Moses to Aaron and to his sons, Tel.ing them and those who will follow them not to drink when serving in the temple.
