TSK · Leviticus 23:7

You must present a gift to the LORD for seven days, and the seventh day is a holy assembly; you must not do any regular work.’”

You must not do any regular work, but you must present a gift to the LORD.

For seven days you must present a gift to the LORD. On the eighth day there is to be a holy assembly for you, and you must present a gift to the LORD. It is a solemn assembly day; you must not do any regular work.

Blowing Trumpets“‘On the first day of the seventh month, you are to hold a holy assembly. You must not do your ordinary work, for it is a day of blowing trumpets for you.
