Exodus 17:1-17

The Israelites come to another point of need, and they respond how they always did - with fear, entitlement and grumbling. 

Moses cries out to God, and God answers by doing another miracle.

This miracle, however, was meant to foreshadow a bigger miracle that God would do through Jesus one day - the miracle of giving living water to the thirsty souls of all who would come to Him and drink.
