'Divisions' in the Bible

The next day Saul organized the troops into three divisions. During the morning watch, they invaded the Ammonite camp and slaughtered them until the heat of the day. There were survivors, but they were so scattered that no two of them were left together.

Raiding parties went out from the Philistine camp in three divisions. One division headed toward the Ophrah road leading to the land of Shual.

And Saul turneth back from pursuing after David, and goeth to meet the Philistines, therefore they have called that place 'The Rock of Divisions.'
