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).
Psalm 65:9–13 closes the song with a focus on God's providential care of the earth and gracious provision for mankind. The Lord faithfully prepares the earth for harvest. Evidence of His goodness is clearly seen in nature (Romans 1:18–20; Psalm 19:1). Likewise, the Lord should be given credit for what farms and fields produce (1 Corinthians 3:7). This passage seems a straightforward praise to the Lord for good crops. At the same time, this passage foreshadows the eternal, spiritual blessings which come through God's grace (John 4:36; James 3:18; Galatians 6:8).
David begins by anticipating praise to the Lord, expecting that He will bring atonement, fellowship, and blessing. The psalm mentions God's miraculous examples before referring to various natural examples of His provision. These benefits are both visible and available to all people of the world.
