As you read the passage below notice the connection between faithfulness to the Lord and God speaking clearly to that faithful person. Pay special attention to verses 7-8 where faithfulness results in God speaking to Moses very clearly.
Numbers 12:1-8
Then Miriam and Aaron spoke against Moses because of the Cushite woman whom he had married (for he had married a Cushite woman); 2 and they said, "Has the Lord indeed spoken only through Moses?

Even openly, and not in dark sayings,
And he beholds the form of the Lord.
Why then were you not afraid
To speak against My servant, against Moses?"
