The journey from Kadesh Barnea to the crossing of the Zered Valley took 38 years, a significant period in Israel's history. This time frame was marked by the passing of the generation of fighting men who had initially doubted God's promise to deliver the Promised Land to them. Their disbelief and lack of faith led to their exclusion from entering the land, as God had declared. This verse highlights the fulfillment of God's word and serves as a poignant reminder of the consequences of disobedience and lack of faith.
As the Israelites prepared to cross the Zered Valley, a new generation was emerging, one that had not experienced the initial exodus from Egypt but had grown up in the wilderness. This transition signifies a shift from an era of doubt to one of renewed hope and trust in God's promises. The verse underscores the importance of faithfulness and obedience to God, illustrating that while God's promises are sure, they require a response of trust and commitment from His people. It also serves as a testament to God's patience and enduring faithfulness to His covenant, as He prepares to fulfill His promise to the new generation.
