'Convocation' in the Bible

‘For six days work may be done, but the seventh day is the Sabbath of complete rest, a holy convocation (calling together). You shall not do any work [on that day]; it is the Sabbath of the Lord wherever you may be.

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].’”

The first day is a holy convocation (calling together); 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].
