Deuteronomy 20:2 "And it shall be when you come near to the Battle the priest shall approach and speak to the people"

The army base was very busy with activity.

An air raid on unfriendly territory was scheduled that night.

Arms were distributed, equipment was double checked, instructions were handed down and the soldiers were training in a mock attack.

Officers were marking targets on their maps and the plan was being finalized.

The Priest, is commanded to stand before the troops and prepare them for combat.

He encourages and inspires the soldiers to put their trust in HaShem and fight with courage.

He excuses weak and nervous soldiers from combat duty because they might spread fear and panic among the other soldiers.

The Torah also releases certain other soldiers for various reasons.
