Numbers 20 was filled with heartache. Thankfully, all did not remain dark for chapter 21 contains a great deal of encouragement. Though it recounts a sinful episode (vv. 4–9), it nonetheless also contains grace and forgiveness, military conquest, gracious divine provision, a song of celebration, and a wonderful fulfilment of prophecy. All things considered, this chapter is thematically about hope and new beginnings. Its theme is hope renewed.
