This paper deals with conflicts and reconciliation between Edom and Israel. Edom and Israel have historically had many conflicts. The Genesis saw the cause of the conflict as a struggle for leadership, the Books of Prophecy as evil activities between Edom and Israel, and the Books of History as a matter of land and resources. In particular, the prophecy shows extreme hostility toward Edom, whose main cause is a sense of betrayal toward Edom rather than the fault it committed against Israel. In order to resolve these conflicts between the neighboring countries, the prophecy summons memories of brotherhood and continues its desire for reconciliation. Meanwhile, Genesis tells the story of Esau and Jacob’s meeting that unconditional forgiveness must precede reconciliation. Also, the story of the reunion tells us that recognizing each other’s territory is the way to sustain reconciliation. Reconciliation can continue when you stop fighting for leadership and recognize your opponent’s territory. From this point of view, it can be said that this paper can present the Old Testament principle of achieving reconciliation between conflicting communities.
