'Assemble' in the Bible

You are to bring the Levites before the tent of meeting and assemble the entire community of the Israelites.

But when you assemble the community, you must blow, but you must not sound an alarm.

"Take the staff and assemble the community, you and Aaron your brother, and then speak to the rock before their eyes. It will pour forth its water, and you will bring water out of the rock for them, and so you will give the community and their beasts water to drink."
