They said to Joshua, Truly Yahweh has delivered into our hands all the land; and moreover all the inhabitants of the land do melt away before us.
The report of these spies to Joshua must have been a source of infinite encouragement to the Commander.  Up to here, Joshua could have supposed that a military assault would be necessary, but, after this report, he no doubt sought to know the will of God by every means open to him.  In these circumstances, God spoke directly to Joshua  (Joshua 3:7) with specific instructions on how the conquest was to proceed.
