'Laborious' in the Bible

On the first day you shall have a holy convocation (calling together); you shall not do any laborious work [on that day].

But you shall present an offering by fire to the Lord for seven days; on the seventh day there shall be a holy convocation; you shall not do any laborious work [on that day].’”

For seven days you shall present an offering by fire to the Lord. On the eighth day you shall have a holy convocation and present an offering by fire to the Lord. It is a festive assembly; you shall not do any laborious work [on that day].
