[30:10]  ¹ tn The word “atonements” (plural in Hebrew) is a genitive showing the result or product of the sacrifice made.

[30:10]  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.

[30:10]  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.

[30:21]  ⁴ tn Heb “and [then] they will wash.”

[30:21]  ⁵ tn The verb is “it will be.”

[30:21]  ⁶ tn Heb “for his seed.”

[30:21]  ⁷ tn Or “for generations to come”; it literally is “to their generations.”

[30:21]  sn The symbolic meaning of washing has been taught throughout the ages. This was a practical matter of cleaning hands and feet, but it was also symbolic of purification before Yahweh. It was an outward sign of inner spiritual cleansing, or forgiveness. Jesus washed the disciples feet (Jn 13) to show this same teaching; he asked the disciples if they knew what he had done (so it was more than washing feet). In this passage the theological points for the outline would be these: I. God provides the means of cleansing; II. Cleansing is a prerequisite for participating in the worship, and III. (Believers) priests must regularly appropriate God’s provision of cleansing.
