The word translated "meditate" in Psalm 1:2 is the Hebrew word hagah. It carries the picture of a low, murmuring sound — like a dove cooing, or a lion growling over its prey. It is also used to describe the rumination of an animal — bringing something up again and again to digest it fully.
Biblical meditation is not the emptying of the mind. It is the filling of the mind with the Word of God, and then turning it over, examining it from different angles, letting it connect to other passages, asking questions of it until it begins to yield its riches.
Here is a simple practice that works. Choose one verse. Read it slowly. Ask: What does this say about God? What does it say about me? What does it call me to do or believe? Then return to it throughout the day. In the car. While waiting. Before you fall asleep.
The person who does this — even with just one verse — will find that the Word begins to form thoughts, shape responses, and reorient priorities in ways that a single daily reading cannot. Psalm 1 says this person is "like a tree planted by streams of water." Not struggling to survive. Deeply rooted. Fruitful in season.
The text is inexhaustible. You cannot exhaust a passage of Scripture by meditating on it. You can only go deeper.
