They returned to Joshua, and said to him, Don't let all the people go up; but let about two or three thousand men go up and strike Ai; don't make all the people to toil there; for they are but few.
The spies in Numbers 13, 14 lacked faith in God because they did not believe that the Israelites were strong enough to defeat their enemies. They failed to reckon on God’s help. The spies in Joshua 7 lacked faith in God because they believed the Israelites were strong enough to defeat their enemies. They disregarded the need for God’s help. The fact that the people’s hearts melted (Joshua 7:5; cf. Joshua 2:11) hints that Israel may have been trusting in her own strength rather than in the Lord.
