'Assemble' in the Bible

So you shall present the Levites before the tent of meeting. You shall also assemble the whole congregation of the sons of Israel,

Yet if only one is blown, then the leaders, the heads of the divisions of Israel, shall assemble before you.

“Take the rod; and you and your brother Aaron assemble the congregation and speak to the rock before their eyes, that it may yield its water. You shall thus bring forth water for them out of the rock and let the congregation and their beasts drink.”

From there they continued to Beer, that is the well where the Lord said to Moses, “Assemble the people, that I may give them water.”
