God was leading Moses & his people to the Promise Land.
They got weary, discouraged & they were very thirsty.
People started to murmur against Moses & God again.
God said, "Tell this rock to give the water".
But Moses was so upset, that he smote the rock. The refreshing water came out.
God was displeased with Moses because Moses was angry.
God told him that because of his disobedience, Moses would not come into the Promise Land.
