Lose it all. The people of Edam are going to lose everything they have, and it will go to those who have been their enemies. Read Obadiah 1:19.
Then those of the Negev will possess the mountain of Esau, And those of the Shephelah the Philistine plain; Also, possess the territory of Ephraim and the territory of Samaria, And Benjamin will possess Gilead.
Obadiah 1:19 NASB
Because of their disobedience, part of the judgment that God is bringing upon the people of Edom will be that they will lose everything they have. Prior verses have talked about them losing their fields and their crops, but now they will lose even the land itself.
When God brings judgment for sin, it is complete. God does not partially judge things. He completely judges it. We can not only partially fulfill what God has given us, because to him we are either completely obedient or completely disobedient. Thankfully, Jesus Christ came and lived the perfect life that we could not live so that we would have the opportunity to ask forgiveness and through his grace, allow him to save us. Have we accepted this gift from Jesus Christ today?
