'Sentries' in the Bible

After this, you will come to the Gibeah of God, where there are sentries of [the] Philistines. {Just as you enter} the town there, you will meet a procession of prophets coming down from the high place, with harp, tambourine, flute, and zither before them, and they will be prophesying.

Saul's sentries in Gibeah of Benjamin watched as the camp was in disarray, going this way and that.
