Therefore I will take back my grain in its time, And my new wine in its season, And will pluck away my wool and my flax which should have covered her nakedness.
As in, after the Great Tribulation period when the Lord returns and these people then come from the wilderness, they will make their way back up into Israel through this valley of Achor and there they will be singing as they did years ago in the times of Joshua as they were coming into the land that God had promised, with singing and rejoicing. So, therefore, they shall come and sing in the heights of Zion and this glorious day in the future.
