Numbers 28:24-26

Amplified Bible

²⁴ In this way you shall present daily, for seven days, the food of the offering by fire, a sweet and soothing aroma to the Lord; it shall be presented with its drink offering in addition to the continual burnt offering. ²⁵ On the seventh day you shall have a holy [summoned] assembly; you shall do no laborious work.

²⁶ ‘Also on the day of the first fruits, when you offer a new grain offering to the Lord at your Feast of Weeks, you shall have a holy [summoned] assembly; you shall do no laborious work.
