'Groups' in the Bible

Then he ordered them to have all the people sit down in groups on the green grass.

So they sat down in groups of hundreds and fifties.

Now there were about 5,000 men. So he told his disciples, "Have them sit down in groups of about 50."

For it is he who is our peace. Through his mortality he made both groups one by tearing down the wall of hostility that divided them.

and reconciling both groups to God in one body through the cross, on which he eliminated the hostility.
