Gossiping doesn’t seem like such a big deal, and hardly seems like a sin. What harm can it do when it’s spoken of in private? The truth is, it’s not in private; God hears every word, and to speak disparagingly about any of his beloveds, is like spitting in his face. How much do you really know about a person and their plight, that you should make a judgement upon them through negative talk? Why is someone else the topic of your conversation? Shouldn’t you be more concerned with your own issues?
Miriam spoke to Aaron about Moses in a negative way because of who he chose to marry, and God heard her! She may have also been a bit jealous of his personal relationship with God, because he met him face to face, and not in dreams and visions as with others. God called Miriam, Aaron, and Moses together and confronted them; he also admonished Aaron, who was the hearer, but Miriam was given leprosy and had to be quarantined for seven days outside of the camp. God embarrassed her because of her loose tongue. This is a very good lesson against gossip, we would all do well to heed God’s warning.
And the anger of the LORD was kindled against them, and he departed. When the cloud removed from over the tent, behold, Miriam was leprous, like snow. And Aaron turned toward Miriam, and behold, she was leprous. Numbers 12:9-10
