In this passage, God is providing reassurance to the Israelites as they prepare to enter the Promised Land. By recalling the defeat of Sihon and Og, two powerful kings who previously opposed them, God is reminding His people of His mighty acts and His ability to deliver them from formidable enemies. This historical reference serves as a powerful reminder that God is faithful and capable of overcoming any obstacle.
The mention of these past victories is meant to bolster the Israelites' faith, encouraging them to trust in God's promises and His ongoing presence with them. It underscores a central theme in the Bible: God's faithfulness and power are constant, and He is committed to fulfilling His promises to His people. For believers today, this passage serves as a reminder to look back at God's faithfulness in their own lives as a source of encouragement and strength when facing new challenges. It emphasizes that God is unchanging and His promises remain true, offering assurance and hope for the future.
