'Approach' in the Bible

When you approach {the border of} the {Ammonites}, you shall not harass them, and you shall not get involved in battle with them, for I have not given the land of {the Ammonites} to you as a possession; because I have given it to the descendants of Lot [as] a possession.

Only the land of {the Ammonites} you did not approach, [all along] the whole upper region of the Jabbok {River} and the towns of the hill country, [according to all] that Yahweh our God had instructed.

{And then} when you approach the battle, then the priest shall come near and speak to the troops.

"When you approach a city to fight against it, {you must offer it peace}.
