What does Psalm 65:10 mean?

David acknowledges God's role in bringing about an abundant harvest. Farmers plant, but their efforts would be unproductive without water. Fortunately, God provides the rain and river water which fills the irrigation ditches and the pipelines that allow farmers to water their fields. He writes that God waters the cultivated land's furrows: the grooves and ruts made by farmers. This softens what otherwise would be dead, dusty ground. As a result of the Lord's providential provision of water, that which farmers plant can grow and bless the consumers of its harvest (Genesis 2:6, 10; 27:28).

The book of Ruth unfolds the story a Moabite who scavenged in grain fields belonging to a man named Boaz. Boaz is called "a worthy man" in Ruth 2:1. His grain fields were so productive that he gave his reapers orders to leave some of the harvest behind for Ruth. (Ruth 2:16). As a result of Boaz's kindness, Ruth had enough food for herself and her mother-in-law (Ruth 2:17–18).
