'Groups' in the Bible

As for the working groups of the gatekeepers: of the Korahites, Meshelemiah the son of Kore, from the sons of Asaph.

These working groups of gatekeepers, corresponding to the chief men, had responsibilities like their brothers to serve in the house of Yahweh.

These [were] the working groups of the gatekeepers among the sons of the Korahites and among the sons of Merari.

And as for the number of the {Israelites}, the heads of {families}, the commanders of thousands and hundreds, and their officials who serve the king in all matters of the working groups that came and went, month by month, throughout all the months of the year, each working group: twenty-four thousand.

And over the working groups of the second month: Dodai the Ahohite and his working group, and Mikloth the commander. And [he was] over his working group [of] twenty-four thousand.

Then David assembled all the commanders of Israel, the commanders of the tribes and the commanders of working groups who served the king, and the commanders of thousands, the commanders of hundreds, and the commanders over all the property of the king and his sons, with the court officials and mighty warriors, and all the mighty warriors of ability, at Jerusalem.

and for the working groups of the priests and the Levites, and for all the work of the service of the house of Yahweh, and for all the vessels for the service of the house of Yahweh,

And behold, the working groups of the priests and the Levites for all the service of the house of God; and with you in all the work for all [those] willing with the skill for every service, and the commanders and all the people for all your commands."
