My goodness, and my fortress; my high tower, and my deliverer; my shield, and he in whom I trust. The general resemblance to Psalms 18:2 is striking, but there are peculiar and original touches which indicate the author, not the copyist.
For instance, the expression, "my goodness," occurs nowhere else. Who subdueth my people under me. Another reading gives, "Who subdueth peoples under me." Either reading suits the circumstances of David, who had to subdue a great portion of his own people under him (2 Samuel 2:8-31; 2 Samuel 3:6-21), and also conquered many foreign nations (2 Samuel 8:1-14).
