The document provides commentary from multiple scholars on Joshua 6:1, which describes Jericho as being "straitly shut up" due to the Israelites. The scholars discuss the context around Jericho shutting its gates tightly out of fear of the Israelites. They also analyze the significance of God's instructions to Joshua to have the Israelites march around Jericho for six days and then seven times on the seventh day, which resulted in Jericho's walls falling down. The commentaries examine themes of God's power overcoming human fortifications, the importance of obedience to God's commands through faith even without understanding the outcome, and the need for perseverance in faith.
