Aaron and his sons must wear them whenever they enter the tent of meeting or approach the altar to minister in the Holy Place, so that they will not incur guilt and die.
“This is to be a lasting ordinance for Aaron and his descendants.
Exodus 28 | NIV Bible | YouVersion
“Anoint Aaron and his sons and consecrate them so they may serve me as priests. 31Say to the Israelites, ‘This is to be my sacred anointing oil for the generations to come. 32Do not pour it on anyone else’s body and do not make any other oil using the same formula. It is sacred, and you are to consider it sacred. 33Whoever makes perfume like it and puts it on anyone other than a priest must be cut off from their people.’ ”
Exodus 30 | NIV Bible | YouVersion
Interesting I found that the Bible says they were meant to be only priests, and priests means exalted leader:
But didn’t you drive out the priests of the LORD, the sons of Aaron, and the Levites, and make priests of your own as the peoples of other lands do? Whoever comes to consecrate himself with a young bull and seven rams may become a priest of what are not gods.
And is psalms:
Let the house of Aaron say: “His love endures forever.”
Yet Aaron with his sister is accused of speaking against Moses to the extent Miriam dies of leprosy...
And we see God is angry at Aaron and his sons here and retracts some of the position they were given:
Leviticus 10 - NIV Bible - Aaron’s sons Nadab and Abihu took their censers,... (biblestudytools.com)
Also, the original prayer of Moses was regarding his tongue which he wanted the knot relieved regarding "by the one who you will send", but God said you have Aaron. So how can Aaron not live after Moses, when it's obviously not about a physical defect but about Moses being able to convey the truth fully and enlighten people, instead of waiting for the one God will send, he said you have Aaron who you must pray instead that he will relieve the knot of your tongue.
