'Units' in the Bible

God chose new leaders, then fighters appeared in the city gates; but, I swear, not a shield or spear could be found, among forty military units in Israel.

He divided the three hundred men into three units. He gave them all trumpets and empty jars with torches inside them.

All three units blew their trumpets and broke their jars. They held the torches in their left hand and the trumpets in their right. Then they yelled, "A sword for the Lord and for Gideon!"

So Abimelech and all the people with him got up at night and waited in ambush for Shechem in four units.

he took his men and divided them into three units and set an ambush in the field. When he saw the people coming out of the city, he attacked and struck them down.

Then Abimelech and the units that were with him rushed forward and took their stand at the entrance of the city gate. The other two units rushed against all who were in the countryside and struck them down.
