Promise 13 from Numbers 12:6-9

Numbers 12:6-9 - "He said, 'Hear now My words: If there is a prophet among you, I, the Lord, shall make Myself known to him in a vision. I shall speak with him in a dream. Not so, with My servant Moses, He is faithful in all My household' With him I speak mouth to mouth, 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?' So the anger of the Lord burned against them and He departed."

Miriam and Aaron were complaining about Moses' choices of wife and God heard them. So He called the two and Moses to join Him for a sit down at the tent of meeting. God is showing them who His favourite is, He says, 'If I were to speak to you guys, I would speak through you as a prophet by way of vision and dreams of Myself, but not my buddy Moses, we have face to face chats, I let Him see Me." Then He says, "So how do you even have the gall to raise a complaint against My buddy, My favourite one?" Its like He is saying, "Do you not realise who you are complaining against? You are complaining against your Creator's best friend." And He shows His anger and punishes Miriam by putting leprosy on her, just long enough to scare her and Aaron. God goes to bat for His friends. He sticks up for Moses, affirms Him and does not allow the complaint to go any further than what was spoken out. But He also takes the complaint personally. When a complaint rises against His humble servants (see vv.3), then it rises against Him as well. The complainers demonstrate a lack of respect for the actions or decisions the complainee made, therefore they complain against God's role in leading that decision, thereby showing a lack of respect for God. God is not going to allow leaders of people to follow through and lead others into a lack of respect for Him and His ways. He also is not going to let them lead others into a lack of respect for His chosen servants, His friends. He will bring justice and righteousness into the situation and snuff out the complaint.
