'Group' in the Bible

The priest was happy. He took the ephod, the personal idols, and the carved image and joined the group.

We will take ten of every group of a hundred men from all the tribes of Israel (and a hundred of every group of a thousand, and a thousand of every group of ten thousand) to get supplies for the army. When they arrive in Gibeah of Benjamin they will punish them for the atrocity which they committed in Israel."
