The answer is: Psalm 23

Psalm 23:2 - This beloved psalm portrays God as a shepherd, illustrating His care and provision. The image of green pastures evokes peace and rest, echoing Isaiah 40:11 where God tends His flock, demonstrating His nurturing nature. David's deep faith resonates throughout Scripture, reflecting the relationship between God and His people.

Psalm 23, with its picturesque imagery of lying down in lush green pastures, is perhaps one of the most famous pieces of Scripture. It beautifully captures the essence of divine care, casting God as a gentle shepherd who guides and comforts His followers. This metaphor of shepherding is rich in biblical tradition, linking back not only to David—who was a shepherd himself—but also to Moses, who learned patience tending sheep before leading the Israelites. It's fascinating to note that the role of a shepherd in ancient societies involved great responsibility, highlighting the worthiness of trust bestowed upon them.

Furthermore, this Psalm doesn’t just skim the surface. Much like a great symphony, it harmonizes various themes: trust, peace, restoration, and guidance. For instance, the phrase about lying down also reflects a deeper aspect of restoration. Sheep must feel safe to graze peacefully; if predators lurk nearby, they'll never lie down. This idea speaks volumes about the safety and security found in faith.

Beyond Psalm 23, this depiction of a shepherd is echoed in other parts of the Bible, notably in John 10:11, where the figure of Jesus refers to himself as the "Good Shepherd," drawing us even further into that divine care—strengthening the bond between God and humanity. Who would have thought that these beautiful passages echo across such vast moments in Biblical text, urging us toward serenity and trust? It's an invitation to reflect on how spiritual sustenance is quite like a velvety pasture—a necessary comfort we all seek.
