Deuteronomy 20:2

And it shall be, when ye draw nigh unto the battle, that the priest shall approach and speak unto the people,

When you are about to engage in battle, the priest is to come forward and address the army.

And when you draw near to the battle, the priest shall come forward and speak to the people

And it shall be, when ye are come nigh unto the battle, that the priest shall approach and speak unto the people,

When you are approaching the battle, the priest shall come forward and speak to the people.

When you are about to go into battle, the priest shall come forward and address the army.

So it shall be, when you are on the verge of battle, that the priest shall approach and speak to the people.

When you prepare for battle, the priest must come forward to speak to the troops.
