But now this is the thing that we will do to Gibeah: go up against it by lot, Bible

“by lot.” That is, by allowing the High Priest to use his breastplate and draw the Urim or Thummim out of it and thus make decisions. The land of Israel was divided by lot in Joshua. This shows that the people were drawing God into the situation and allowing Him to make battle choices.
