Surely I have behaved and quieted myself; rather, I have stilled and quieted my soul. I have brought my soul into a state of peacefulness and content. As a child that is weaned of his mother. The weaned child is quiet and content; the suckling always impatient and restless.
My soul is even as a weaned child. Another repetition for the sake of emphasis (see Psalms 130:5, Psalms 130:6).
