Imamat 23:31

23:31 You must not do any work. This is a perpetual statute throughout your generations ¹  in all the places where you live.

Bilangan 29:7

The Day of Atonement

29:7 “‘On the tenth day of this seventh month you are to have a holy assembly. You must humble yourselves; ²  you must not do any work on it.

[23:31]  ¹ tn Heb “for your generations.”

[29:7]  ² tn Heb “afflict yourselves”; NAB “mortify yourselves”; NIV, NRSV “deny yourselves.”

[29:7]  sn The verb seems to mean “humble yourself.” There is no explanation given for it. In the days of the prophets fasting seems to be associated with it (see Isa 58:3-5), and possibly the symbolic wearing of ashes.
