Charles H. Spurgeon on Psalms 62:9

Lighter than vanity. If there were any one among men immortal, not liable to sin, or change, whom it were impossible for any one to overcome, but who was strong as an angel, such a one might be something; but inasmuch as every one is a man, a sinner, mortal, weak, liable to sickness and death, exposed to pain and terror, like Pharaoh, even from the most insignificant animals, and liable to so many miseries that it is impossible to count them, the conclusion must be a valid one: "Man is nothing." Arndt.
