'Assembly' in the Bible

and ye shall keep it until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at even.

and the children of Israel said unto them, Would that we had died by the hand of Jehovah in the land of Egypt, when we sat by the flesh-pots, when we did eat bread to the full; for ye have brought us forth into this wilderness, to kill this whole assembly with hunger.
