'Group' in the Bible

Asa cried out to the LORD his God, telling him, "LORD, there is no one except for you to help between the powerful and the weak. So help us, LORD God, because we're depending on you and have come against this vast group in your name. LORD, you are our God. Let no mere mortal man defeat you!"

Everybody went to Jerusalem, and the whole group made a covenant with the king in God's Temple, where Jehoiada addressed them:

AN OFFICIAL STATEMENT FROM CYRUS, KING OF PERSIA All of the kingdoms of the earth have been given to me by the LORD God of Heaven, and he specifically charged me to build a temple for him in Jerusalem, which is in Judah. Therefore, who among the LORD's people trusts in his God? Whoever among this group wishes to do so may travel to Jerusalem.
