Aaron and Miriam got distracted. They allowed a bitter root to spring up. It defiled their inner being. They criticized Moses, and discussed it together. I think of Numbers 12 as God taking Aaron and Miriam to the woodshed.

He questioned their hearts after He heard their conversation. Verse 8 says, “…Why then were you not afraid to speak against My servant Moses?” I have to use this verse myself when I want to complain in my mind about others. 

Mental dialogue against anyone or any circumstance is sin. Don’t get distracted! Romans 14:4 is a verse that I view as a momma cat carrying a kitten in her mouth. The kitten can’t speak or move. It says, “Who are you to judge another’s servant? To his own master he stands or falls…”

Matthew 7:2 says, “For with what judgment you judge, you will be judged…” I certainly don’t want that noose around my neck.
