What does Isaiah 17:6 mean?
The northern nation of Israel (1 Kings 12:16–20) will experience drastic change after they share in the judgment of the Lord against Damascus and Syria. The prophet Isaiah has said that their "glory" will be brought low (Isaiah 17:3–4).Apparently, the people of Israel had been living in some abundance before the Assyrians destroyed so much of their nation. They had been thriving. Afterwards, Isaiah describes the survivors as those who live off the gleanings of the harvest. He described how the poor would gather the dropped ears of grain left behind by the reapers (Isaiah 17:5). Now he shows how they would have to work to get the few berries left behind during the olive harvest.
Olives were harvested by beating the trees with sticks once the berries were ripe enough to fall to the ground from their own weight. Berries too high up in the tree though would be missed. The poor could climb the tree to get to them for needed food.
The law of Moses mandated a specific practice as a way of providing for the poor:
"When you reap your harvest in your field and forget a sheaf in the field, you shall not go back to get it. It shall be for the sojourner, the fatherless, and the widow, that the Lord your God may bless you in all the work of your hands. When you beat your olive trees, you shall not go over them again. It shall be for the sojourner, the fatherless, and the widow. When you gather the grapes of your vineyard, you shall not strip it afterward. It shall be for the sojourner, the fatherless, and the widow." (Deuteronomy 24:19–21)
Following the Lord's judgment, His once wealthy people will be reduced to barely surviving on the scraps of others.
