Isaiah 24 prophesies that God will preserve a remnant made up of grape gleanings (the His Church) and of olives (national Israelites) who will sing together.
Isaiah's apocalypse resembles Exodus, as both begin with a narration of God's judgment on sinners and then move to a description of God's continuing work.
In Boaz' instructions to Ruth, we see the concern of Christ for His people. These instructions will keep us nourished, satisfied, and safe from harm.
