Over the last several chapters, God has sought to refocus Elijah on the true reality of justice, love, and mercy, and not on defending himself and his beliefs using the name of God. In the story of Naboth, we finally see Elijah getting the point.
In the story of the widow, we should see Advent. We have a humble and intimate story. God working through small things – birds and the small gifts of a poor widow. The characters are mundane, and the location is marginal. Small people doing small things in unlikely places. And through them, God invades enemy-occupied territory to bring dead things back to life.
