'Assembly' in the Bible

You shall keep it until the fourteenth day of the same month, then the whole assembly of the congregation of Israel is to kill it at twilight.

On the first day you shall have a holy assembly, and another holy assembly on the seventh day; no work at all shall be done on them, except what must be eaten by every person, that alone may be prepared by you.

The sons of Israel said to them, “Would that we had died by the Lord’s hand in the land of Egypt, when we sat by the pots of meat, when we ate bread to the full; for you have brought us out into this wilderness to kill this whole assembly with hunger.”
