Today's reading is a lament about the failings of the chosen people to live up to God's hopes and expectations. God's people are compared to a vineyard, carefully planted and tended, but which yields only wild grapes. The parallel is clear: the Jews had received God's blessings and protection -- especially the Promised Land. Despite many opportunities, they failed to develop into the free and faithful people God desired. So, now God is cutting the loss. Like a planter who abandons a vineyard that does not adequately produce, so God is abandoning the chosen.people.
