'Assemble' in the Bible

And thou shalt present the Levites before the tent of meeting: and thou shalt assemble the whole congregation of the children of Israel:

Take the rod, and assemble the congregation, thou, and Aaron thy brother, and speak ye unto the rock before their eyes, that it give forth its water; and thou shalt bring forth to them water out of the rock; so thou shalt give the congregation and their cattle drink.
