Exodus 30:10

30:10 Aaron is to make atonement on its horns once in the year with some of the blood of the sin offering for atonement; ¹  once in the year ²  he is to make atonement on it throughout your generations. It is most holy to the Lord.” ³ 

Hebrews 5:1

5:1 For every high priest is taken from among the people ⁴  and appointed ⁵  to represent them before God, ⁶  to offer both gifts and sacrifices for sins.

Hebrews 5:3

5:3 and for this reason he is obligated to make sin offerings for himself as well as for the people.

¹ tn The word “atonements” (plural in Hebrew) is a genitive showing the result or product of the sacrifice made.

² sn This ruling presupposes that the instruction for the Day of Atonement has been given, or at the very least, is to be given shortly. That is the one day of the year that all sin and all ritual impurity would be removed.

³ sn The phrase “most holy to the Lord” means that the altar cannot be used for any other purpose than what is stated here.

⁴ tn Grk “from among men,” but since the point in context is shared humanity (rather than shared maleness), the plural Greek term ἀνθρώπων (anqrwpwn) has been translated “people.”

⁵ tn Grk “who is taken from among people is appointed.”

⁶ tn Grk “appointed on behalf of people in reference to things relating to God.”
