What does 1 Samuel 25:29 mean?

Even if someone tries to hunt you down and take your life, the Lord your God will keep you safe, like someone carefully protecting something precious. But your enemies will be thrown away like stones from a sling. 1 Samuel 25:29 - Modern Text Bible

(Abigail reassures David that God will protect him from harm, while his enemies will be cast aside. She uses vivid imagery to show God's care and the fate of those who oppose David.)
