Joshua 7:5 What does it mean for the peoples hearts to be like water

Question: the hearts of the people melted and became like water, what does it mean by this in Joshua 7:5


This simply means that the people of Israel where fearful, because even though they had a superior amount of men to fight the battle, they lost.  And they realized that God was not with them (because there was sin in the camp Joshua 7:1).  This brought fear in them.  Just as water is not solid… so too was their hearts, there was not strength found in them. -JH
