In this passage, we see a continuation of the narrative detailing the lands conquered by the Israelites. Sihon was a king of the Amorites, a group that opposed Israel's passage through their territory. The Israelites, under God's guidance, defeated Sihon and took possession of his lands. This victory was significant as it marked a step towards the fulfillment of God's promise to Abraham regarding the land for his descendants.
The mention of Heshbon and the border of the Ammonites provides a geographical context, emphasizing the real and historical nature of these events. It also illustrates the strategic importance of these territories, which were crucial for the Israelites as they established themselves in the Promised Land. This passage encourages believers to trust in God's promises and His timing, as He is faithful to fulfill what He has spoken, often in ways that are beyond human understanding.
