'Holy Convocation' in the Bible

“Speak to the children of Israel and say to them, ‘The appointed times (established feasts) of the Lord which you shall proclaim as holy convocations—My appointed times are these:

‘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.

‘These are the appointed times of the Lord, holy convocations which you shall proclaim at their appointed times:

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].

‘These are the appointed times (established feasts) of the Lord, which you shall proclaim to be holy convocations, to present an offering by fire to the Lord, a burnt offering and a grain offering, sacrifices and drink offerings, each on its own day.
