Eating Rocks?

Psalm 37:1-9

¹ Don’t get upset over evildoers; don’t be jealous of those who do wrong, ² because they will fade fast, like grass; they will wither like green vegetables. ³ Trust the LORD and do good; live in the land, and farm faithfulness. ⁴ Enjoy the LORD, and he will give what your heart asks. ⁵ Commit your way to the LORD! Trust him! He will act ⁶ and will make your righteousness shine like the dawn, your justice like high noon. ⁷ Be still before the LORD, and wait for him. Don’t get upset when someone gets ahead someone who invents evil schemes. ⁸ Let go of anger and leave rage behind! Don’t get upset—it will only lead to evil. ⁹ Because evildoers will be eliminated, but those who hope in the LORD they will possess the land.
