God's Anger Is Kindled and He Strikes Her With Leprosy

In Numbers 12, remember when Miriam and Aaron spoke against Moses? God was so angry at this His anger was kindled against them. In chapter 14 verse 27, how long shall this wicked congregation grumble against me? I've heard the grumblings of the people of Israel, which theygrumble against me. And in these passages, you just see judgment after judgment after judgment. Why? Because God wants to show Himself as holy.
