Most people in life have not developed a heart that understands that there are levels in God and that God's dealing with a man can defer greatly based on what level of relationship that man has with God. It becomes very important, therefore, never to judge a matter based on only available data. Some individuals are in realms with God that pass known data.
The verse speaks about a time when Miriam and Aaron sought to judge Moses, their brother over a matter of breaking the Jewish law. God brings them to account why they were not afraid to speak against his servant. Child of God, resist your tongue in confronting certain men in this life. Some have dealings with God that may be just beyond your level of judgement.
Your level in God determines your ability to judge certain matters.
This is why after you have understood how God deals with individuals, you cease from making personal opinions of men you did not call. Allow God to elevate you in him before you attempt to explain certain things.
Prophetic Declarations.
Hallelujah. Amen
