Definition: A Psalm [or] Song for the sons of Korah. His foundation [is] in the holy mountains.

Explanation: Okay, let’s break down Psalm 87:1 – it’s a really beautiful and powerful verse! Here's what it means in simple terms: Basically, this verse is saying that God is the ultimate foundation and center of everything. Let's unpack it a little: “A Psalm [or] Song for the sons of Korah”: This refers to a specific song or poem written by the Israelites under King David. The name “Korah” means "to rise" or "to ascend," so this psalm was likely about a group of people who were being elevated, perhaps as a blessing or a promise. “His foundation [is] in the holy mountains.” This is the key part! It’s not just any mountain; it's the holy mountains – which are places that God has chosen to be sacred and connected with his presence. So, what does this tell us? It suggests: God is supreme: He isn’t just part of things, he is the source of everything. His power and stability are rooted in him: The “holy mountains” represent a place where God's presence is strongest and most secure. It speaks to divine authority and permanence: This verse conveys a sense of timelessness – that God’s influence isn’t fleeting but endures forever. In a broader sense, it can be interpreted as: God is the ultimate source of truth, order, and stability in the world. He is the foundation upon which everything else is built.
