Keluaran 30:21

30:21 they must wash ¹  their hands and their feet so that they do not die. And this ²  will be a perpetual ordinance for them and for their descendants ³  throughout their generations.” ⁴ 

Keluaran 40:15

40:15 and anoint them just as you anointed their father, so that they may minister as my priests; their anointing will make them a priesthood that will continue throughout their generations.”

[30:21]  ¹ tn Heb “and [then] they will wash.”

[30:21]  ² tn The verb is “it will be.”

[30:21]  ³ tn Heb “for his seed.”

[30:21]  ⁴ 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.
