The theme of Deuteronomy 2-3 is Wilderness and War. Moses reminds the Israelites how their disobedience delayed their journey to the Promised Land, turning what could have taken days into 40 years. Even during the wandering years, God cared for them by keeping their clothes from wearing out and guiding them. In these chapters, we also read about victories over powerful kings like Sihon and Og, which proved God’s strength and showed that battles can prepare us for future challenges. Moses also warns about obeying God completely, as failing to follow instructions—like in his own case—can cost us blessings. These chapters teach us to trust God in hard times, knowing He uses struggles to make us stronger in faith.
