In the tent of meeting ¹  outside the curtain that is before the testimony, Aaron and his sons are to arrange it from evening ²  to morning before the Lord. This is to be a lasting ordinance among the Israelites for generations to come. ³ 

These must be on Aaron and his sons when they enter ¹  to the tent of meeting, or when they approach ²  the altar to minister in the Holy Place, so that they bear no iniquity and die. ³  It is to be a perpetual ordinance for him and for his descendants ⁴  after him. ⁵ 

“And this is yours: the raised offering of their gift, along with all the wave offerings of the Israelites. I have given them to you and to your sons and daughters with you as a perpetual ordinance. Everyone who is ceremonially clean in your household may eat of it.

All the raised offerings of the holy things that the Israelites offer to the Lord, I have given to you, and to your sons and daughters with you, as a perpetual ordinance. It is a covenant of salt ¹  forever before the Lord for you and for your descendants with you.”
