God introduced Himself to Moses through the burning bush, and revealed His power, love, justice and holiness through the exodus, protection from enemies, providing food and water.  All of these incidents that introduce God to His people can be summed up in one event: God's redemption.  God bought these people. 

God has also bought us with the price of His Son, Yeshua.  And Yeshua (Jesus) has become our Lord (Master), who has given to us the exact same job that Moses had: to release the captives from their bondage and lead them out of slavery and into the promised land.
