Did David the prophet practice something similar to the Jesus Prayer?

The answer

He sings, saying, “Oh, how I love Your law. It is my meditation all the day” (Ps. 119:97). “My voice You shall hear in the morning. In the morning I will direct it to You, And I will look up” (Ps. 5:3). “O God You are my God. Early I will seek you” (Ps. 63:1). “Evening, morning, and at noon, I will pray and cry aloud, and He shall hear my voice” (Ps. 55:17).
